Question:
What is the molar mass of KMnO4?
Molar Mass:
Molar mass is the number of grams of a substance that equals one mole or 6.02x1023 molecules, also known as Avogadro's number. Molar mass can be used to convert between moles and grams, denoted by g/mol.
The molar mass of a Potassium permanganate molecule, KMnO₄ is equals to the 158.04 g/mol.
We have a Potassium permanganate molecule, KMnO₄. It consists one atom of potassium, one atom of Manganese and four atoms of oxygen. The mass of one mole of a substance is called its molar mass. Molar mass of a molecule is calculated by the addition of the masses of the individual atoms within the their quantities present in a molecule. So, the molecular mass of KMnO₄, is sum of individual masses of hydrogen, nitrogen and chlorine atoms with number of their atoms. The atomic mass of potassium atom, K
= 39.10 g/mol
The atomic mass of oxygen atom, O = 16 g/mol
The atomic mass of Manganese atom, Mn
= 54.94 g/mol
Now, Molar mass of KMnO₄ = 1× atomic mass of potassium + 1×atomic mass of Manganese + 4× atomic mass of oxygen atom
= 1×K + 1×Mn+ 4×O
= 1×39.10 g/mol + 1×54.94g/mol + 4×16 g/mol
= 39.10 g/mol + 54.94 g/mol + 64 g/mol
= 158.04 g/mol
Hence, the molecular mass of KMnO₄ is 158.04 g/mol.

An analytical chemist is titrating 122.1 mL of a 1.000M solution of nitrous acid (HNO2) with a 0.4000M solution of NaOH. The pK, of nitrous acid is 3.35. Calculate the pH of the acid solution after the chemist has added 344.5 mL of the NaOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of NaOH solution added. Round your answer to 2 decimal places.Calculating the pH of a weak acid titrated with a strong base
The pH of the solution after the addition of 344.5 mL of the NaOH solution is 2.09.
What is Titration Reaction?
Titration is a chemical technique used to determine the concentration of a specific substance in a sample. In a titration, a solution of known concentration (the titrant) is slowly added to a solution of unknown concentration (the analyte) until the reaction between the two is complete. The reaction that takes place during the titration is called the titration reaction.
This is a problem of a weak acid titrated with a strong base. We can use the Henderson-Hasselbalch equation to solve it.
First, we need to calculate the amount of nitrous acid that is present in the initial solution before any NaOH is added. We can use the formula:
moles of HNO2 = 1.000 mol/L x 0.1221 L = 0.1221 moles
The balanced chemical equation for the reaction between nitrous acid and sodium hydroxide is:
HNO2 + NaOH -> NaNO2 + H2O
Since the molar ratio between nitrous acid and sodium hydroxide is 1:1, the amount of sodium hydroxide added is also 0.1221 moles.
Now, we can calculate the concentration of nitrous acid and its conjugate base, nitrite (NO2-), after the addition of NaOH. The volume of the final solution is the sum of the initial volumes of the two solutions:
Vfinal = 122.1 mL + 344.5 mL = 466.6 mL = 0.4666 L
The amount of nitrous acid remaining after the addition of NaOH is:
moles of HNO2 remaining = moles of HNO2 initial - moles of NaOH added
moles of HNO2 remaining = 0.1221 moles - 0.1221 moles = 0 moles
All the nitrous acid has been neutralized by the sodium hydroxide. The amount of nitrite formed is equal to the amount of NaOH added:
moles of NO2- = moles of NaOH added = 0.4000 mol/L x 0.3445 L = 0.1378 moles
The total concentration of nitrite is the sum of the initial concentration and the concentration formed by the reaction:
[NO2-]total = [NO2-]initial + [NO2-]formed
[NO2-]total = 0 + 0.1378 moles / 0.4666 L = 0.2956 M
The concentration of nitrous acid can be calculated using the equilibrium expression for the acid dissociation constant, Ka:
Ka = [H+][NO2-] / [HNO2]
We can assume that the concentration of H+ is negligible compared to the concentration of NO2-, so we can simplify the equation to:
Ka = [NO2-]^2 / [HNO2]
Rearranging the equation and substituting the values, we get:
[HNO2] = [NO2-]^2 / Ka
[HNO2] = (0.2956 M)^2 / 4.5 x 10^-4
[HNO2] = 19.43 M
The pH can be calculated using the Henderson-Hasselbalch equation:
pH = pKa + log([A-]/[HA])b
where pKa = 3.35 is the negative logarithm of the acid dissociation constant, [A-] is the concentration of nitrite (the conjugate base), and [HA] is the concentration of nitrous acid (the weak acid).
Substituting the values, we get:
pH = 3.35 + log(0.2956/19.43)
pH = 3.35 - 1.26
pH = 2.09
Therefore, the pH of the solution after the addition of 344.5 mL of the NaOH solution is 2.09.

A milkman boils milk before distributing it in pots. He raises the temperature of the milk from 10 degrees Celsius to 130 degrees Celsius with the thermal energy of 120000 J. If the mass of the milk Is 25000 g. the specific heat capacity of the milk would be
Answer: The specific heat capacity of the milk is 0.24 J/g°C.
Explanation:
The specific heat capacity (C) of a substance is defined as the amount of heat energy required to raise the temperature of a unit mass of the substance by one degree Celsius. To find the specific heat capacity of the milk in this case, we need to divide the total heat energy added to the milk (120000 J) by the change in temperature of the milk (120 degrees Celsius) and the mass of the milk (25000 g).
Using this formula, the specific heat capacity of the milk can be calculated as follows:
C = (120000 J) / (25000 g * 120°C)
C = (120000 J) / (25000 g * 120 K) (converting Celsius to Kelvin)
C = 0.24 J/g°C
So, the specific heat capacity of the milk is 0.24 J/g°C.

In 1913, Bohr introduced the idea of a quantized electron energy in his model of the hydrogen atom. He suggested that electrons occupy specific, discrete energy levels around the nucleus, and that they can jump between these levels by absorbing or emitting energy. The energy levels are sometimes referred to as electron shells, and the further an electron is from the nucleus, the higher its energy level. This model helped to explain the spectral lines observed in hydrogen emission spectra and became a key concept in the development of quantum mechanics.

The maximum solubility of ag2co3 in 0. 02 m na2co3 is (ksp of ag2co3 is 8 x 10-12).
The maximum solubility of Ag2CO3 in 0.02 M Na2CO3 is 2 x 10^-5 M.
The solubility of a salt can be calculated using its Ksp (solubility product constant) value and the concentration of the ions present in the solution.
The equation for the solubility of silver carbonate (Ag2CO3) in a 0.02 M sodium carbonate (Na2CO3) solution can be written as:
Ag2CO3 (s) → 2Ag+ (aq) + CO3^2- (aq)
Ksp = [Ag+]^2 [CO3^2-]
Since we know the concentration of Na2CO3 (0.02 M),
we can calculate the concentration of CO3^2- ions in the solution:
Na2CO3 (aq) → 2Na+ (aq) + CO3^2- (aq)
[CO3^2-] = 0.02 M
Plugging these values into the Ksp equation:
Ksp = [Ag+]^2 [CO3^2-]
=> [Ag+]^2 * 0.02
[Ag+]^2 = Ksp / [CO3^2-]
=> 8 x 10^-12 / 0.02

what is achieved through the separation of crude oil?
Crude oil separation is a process that involves separating the different components of crude oil into individual fractions.
This process is usually done at an oil refinery using several different methods, including distillation and fractional distillation. Through the separation of crude oil, individual fractions such as gasoline, diesel, and kerosene are produced, which are then used for various purposes.
The first step in crude oil separation is distillation.
Distillation is a process that involves heating crude oil to a high temperature, allowing it to vaporize and separate into different fractions based on their boiling points. This process is typically done in a distillation tower, which is a large cylindrical vessel with a series of trays that the vapor rises through.As the vapor rises, it cools and condenses, eventually forming liquid droplets that fall onto the trays. The trays are arranged in such a way that the heavier, more dense fractions condense and fall onto the trays at the bottom of the tower, while the lighter, less dense fractions condense and fall onto the trays at the top of the tower.

Water may dissolve salt because the positive part of its molecules attracts the negative chloride ions and the negative part of its molecules attracts the positive sodium ions.
The lattice of sodium chloride (NaCl), on the other hand, dissociates into individual ions when it dissolves in water, and these ions are then solved (wrapped) in a layer of water molecules.
NaCl is still thought to dissolve in water because crystalline NaCl can be recovered via solvent evaporation.

Which of the following electron transitions in the hydrogen atom results in emission of light with the shortest wavelength? a. n=1 to n=5
b. n=1 to n=3
c. n=5 to n=1
d. n=3 to n=1
The electron transitions in the hydrogen atom will results in emission of light with the shortest wavelength is n = 3 to n = 1. The correct option is d.
Light is emitted when an electron jumps from the higher orbit to the lower orbit. This is the reason that a and b is not possible.
The expression for the wavelength is as follows :
1/λ = R [1/n1² - 1/n2²]
Wavelength emitted for the transition n = 5 to n = 1 is :
1/λ = R [1/1² - 1/5²]
1/λ = 0.096R
Wavelength emitted for the transition n = 3 to n = 1 is :
1/λ = R [1/1² - 1/3²]
1/λ = 0.89 R
Therefore, electron transitions in the hydrogen atom that results in emission of the light with the shortest wavelength is n = 3 ton = 1. The option d is correct.
