container a holds 717mL of an ideal gas at 2.90atm. container b holds 159mL of a different ideal gas at 4.30atm. if the gases are allowed to mix together, what is the resulting pressure?

If you put 1.50 moles of N2 and 4.00 moles of O2 gas in a 45.0 L container at a temperature of 45°C, the total pressure of the system is 323.1 atm.

The ideal gas law, also known as the general gas equation, is the state equation for a hypothetical ideal gas. Although it has several limitations, it is a good approximation of the behavior of many gases under many conditions.

Given;

N = 5.50 moles

V = 45.0 L

R = gas constant 8.314

T = 318 kelvin

P = ?

By an Ideal gas equation,

PV = nRT

By substituting this values in ideal gas equation, and we get as follows:

P = nRT / V

= 5.50 × 8.314 × 318 / 45.0

= 323.1 atm

Thus, the total pressure of the system is 323.1 atm.

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.

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.

The  reaction rate to the nearest whole number is  352 mg/L/sec. Reaction rate is the pace at which an chemical process moves forward.

Reaction rate is the pace at which an chemical process moves forward. It is frequently described in terms either of the amount of a reactant that's also consumed in a time unit or the intensity of a product that is generated in a unit of time (amount per unit volume). You may also describe it in terms of how much of the reactants are used up or how much of the products are produced in a certain length of time.

at 3°C

Reaction rate = (1000/0.2)/138.5 = 36 mg/L/sec

at 24°C

Reaction rate = (1000/0.2)/34.2 = 146 mg/L/sec

at 40°C

Relative and average atomic mass both describe properties of an element related to its different isotopes. Out of these two Relative atomic mas is more accurate. Therefore, the average atomic mass of copper is 63.55amu.

Mass defines the quantity of a substance. It is measured in gram or kilogram. Average mass is the mass of atoms of an element that are isotopes. It can be calculated by multiplying mass of a isotope to natural abundance of that isotope.

Average atomic mass = (mass of first isotope× percent abundance of first isotope)+(mass of second isotope× percent abundance of second isotope)

Explanation:

The density of nitrogen gas at 67.3 °C and 0.288 atm is approximately 0.0147 g/L.

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

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.

Molality is a term used to express the concentration of a solution. It is the ratio of number of moles of solute to the mass of solvent in kg.

Given the weight of NaCl = 129 g

molar mass = 58.5 g/mol

number of moles = 129/58.5 = 2.20 moles.

Density of solution = 1.08 g/ml

volume of solution  = 1150 ml

then mass of solution = volume  × density = 1150 ×1.08 = 1242 g.

mass of solvent = 1242 -129 = 1113  g = 1.11 Kg.

molality of the solution = 2.2 moles/1.1 Kg = 1.98 molal.

Mass percent of the solution = mass of solute/total mass × 100
