What is the density of nitrogen gas at 67.3 °C and 0.288 atm?
The density of nitrogen gas at 67.3 °C and 0.288 atm is approximately 0.0147 g/L.
What is nitrogen gas used for?
Nitrogen are commonly used during sample preparation in chemical analysis and It also used to concentrate and reduce the volume of liquid sample.
The density of a gas can be calculated using the Ideal Gas Law:
PV = nRT
where P is the pressure, V is the volume n is the number of moles R is the gas constant (8.31 J/molK)T is the temperature in Kelvin.We can rearrange the equation to solve for the volume:
V = nRT / P
And then use the density formula:
density = mass / volume = m / V
where m is the mass of the gas and V is the volume.
Since the moles and the mass of a gas are related by its molecular weight (m = n * MW), we can substitute n * MW for m:
density = (n * MW) / V
Plugging in the values we get:
density = (n * 28.01) / (RT / P)
density = (n * 28.01 g/mol) / ((8.31 J/molK * (67.3 + 273.15 K)) / 0.288 atm)
density = (n * 28.01 g/mol) / (547.57 J/mol / 0.288 atm)
density = (n * 28.01 g/mol) / (1915.69 J/mol / atm)
density = (n * 28.01 g/mol) * (1 atm / 1915.69 J/mol)
density = 0.0147 g/L
Therefore, The density of nitrogen gas at 67.3 °C and 0.288 atm is approximately 0.0147 g/L.

Calculate the mass of oxygen dissolved in 120.0 L
of water at 25 ∘C
at a total pressure of 1 atm
and a mole fraction for oxygen of 0.210. The Henry's law constant for oxygen at 25 ∘C
is 1.3×10−3M/atm
.
Answer: Henry's law states that the solubility of a gas in a liquid is proportional to the partial pressure of the gas over the solution. The relationship can be represented by the equation:
C = kP
where C is the concentration of the gas (in mol/L), k is the Henry's law constant, and P is the partial pressure of the gas.
Given that the mole fraction of oxygen in water is 0.210, the partial pressure of oxygen in the solution is:
P = 0.210 * 1 atm = 0.210 atm
Since the Henry's law constant for oxygen at 25 ∘C is 1.3 × 10^(-3) M/atm, the concentration of oxygen in water can be calculated as:
C = 1.3 × 10^(-3) M/atm * 0.210 atm = 0.000276 M
Finally, the mass of oxygen dissolved in 120.0 L of water can be calculated as:
mass = C * volume * molecular weight of oxygen
= 0.000276 M * 120.0 L * 32.0 g/mol
= 10.57 g

Answer:
X(HCO3)2 is X2(C2H2O6), so the total number of atoms for each element can be calculated:
2 X atoms
4 H atoms
6 C atoms
12 O atoms
Calculate the total atomic mass of the elements:
2 X atoms * atomic mass of X = 2X * atomic mass of X
4 H atoms * 1.0 amu = 4.0 amu
6 C atoms * 12.0 amu = 72.0 amu
12 O atoms * 16.0 amu = 192.0 amu
The molar mass of X(HCO3)2 is 162 g/mol, so the total atomic mass of the elements should add up to 162 g/mol:
2X * atomic mass of X + 4.0 amu + 72.0 amu + 192.0 amu = 162 g/mol
Solve for X by rearranging the equation:
2X * atomic mass of X = 162 g/mol - 4.0 amu - 72.0 amu - 192.0 amu = -12.0 amu
2X = -12.0 amu / atomic mass of X
Divide both sides by 2:
X = -6.0 amu / atomic mass of X
So the relative atomic mass of X is 6.0 amu.

An experiment is set up with a glass bottle and a candle. The starting volume of the bottle is 250 mL at a pressure of 1 atm. The bottle contains 0.00600 moles of O2 gas. A candle is then put into the bottle and the flame consumes most of the oxygen. The temperature is 70°C. After the candle goes out, there is only 0.000540 moles of oxygen remaining and the temperature drops to 35°C. Assume the volume is still 250 mL. What is the pressure inside the bottle?
________atm (use 3 sig figs with one zero in front of the decimal)
30 points
Answer: 0.112 atm.
Explanation:
(PV = nRT), which states that the pressure times volume of a gas is equal to the number of moles of gas times the ideal gas constant times the temperature.
Since the volume of the bottle is constant, we can rearrange the Ideal Gas Law to solve for pressure:
P = (nRT) / V
where
n = 0.000540 moles (the amount of O2 remaining after the candle goes out)
R = 8.31 J/mol*K (the ideal gas constant)
T = 35 + 273 = 308 K (the temperature in kelvins)
V = 250 mL = 0.25 L (the volume of the bottle in liters)
Plugging in the values, we get:
P = (0.000540 * 8.31 * 308) / 0.25
P = 0.112 atm
So, the pressure inside the bottle after the candle goes out is approximately 0.112 atm.

Sulfur trioxide reacts with water to form sulfuric acid according to the following reaction: SO₃ + H₂O → H₂SO₄ Given the atomic mass of hydrogen is 1 amu, the atomic mass of oxygen is 16 amu, and one molecule of sulfuric acid has a mass of 98 amu, what is the atomic mass of sulfur trioxide?
Explanation:
The atomic mass of sulfur trioxide can be calculated as follows:
1 molecule of sulfuric acid has a mass of 98 amu, and it is composed of 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms. So, the mass of hydrogen and oxygen atoms in 1 molecule of sulfuric acid is (2 * 1 amu) + (4 * 16 amu) = 34 amu.
Therefore, the mass of sulfur in 1 molecule of sulfuric acid is 98 amu - 34 amu = 64 amu.
Since 1 molecule of sulfuric acid is formed from 1 molecule of sulfur trioxide, the atomic mass of sulfur trioxide can be calculated as 64 amu.
Sulfur trioxide reacts with water to form sulfuric acid according to the following reaction: SO₃ + H₂O → H₂SO₄ Given the atomic mass of hydrogen is 1 amu, the atomic mass of oxygen is 16 amu, and one molecule of sulfuric acid has a mass of 98 amu, the atomic mass of sulfur trioxide is 80 amu.
According to the law of conservation of mass, in a reaction, atomic mass of the reactants will be equal to atomic mass of the products if the reaction is balanced and above reaction is balanced. Hence,
Mass of SO₃ + Mass of H₂O = Mass of H₂SO₄
x + 18 = 98
x = 80 amu = Mass of SO₃
Therefore, when Sulfur trioxide reacts with water to form sulfuric acid according to the following reaction: SO₃ + H₂O → H₂SO₄ Given the atomic mass of hydrogen is 1 amu, the atomic mass of oxygen is 16 amu, and one molecule of sulfuric acid has a mass of 98 amu, the atomic mass of sulfur trioxide is 80 amu.

How can an electron get from one lobe of a p orbital to the other without going through the point of
zero electron density between them?
An electron get from one lobe of a p orbital because of the wave behavior of the p- orbital, electrons do not cross through the node or point of zero electron density when traveling from one lobe (positive lobe) to the other lobe (negative lobe).
Why is it easier to remove electron from p orbital?The effective nuclear force of attraction is lower with p orbital electrons than with s orbital electrons. As a result, removing an electron from the s orbital requires more energy than removing an electron from the p orbital.
One orbital maximum can have two electrons. Because the s sublevel has only one orbital, it can only hold two electrons. Because the p sublevel has three orbitals, it can hold a maximum of six electrons.
Thus, Electrons can move out between orbits by releasing or absorbing energy.

Fill in the correct conversions for the following temperatures:
298 K =________ °C
________ K = 5°C
335 K =_______ °C
30 points
Answer:
To convert from Kelvin to Celsius, subtract 273 and vice versa to convert from Celsius to Kelvin.
Therefore:
298K - 273 = 24 °C
5°C + 273 = 278K
335K - 273 = 62°C
