Calculation of Relative Molar Mass and Relative Density of Gases

To calculate the relative molar mass and relative density of gases, we need to use the concept of the ideal gas law. The ideal gas law states that the product of the pressure, volume, and temperature of a gas is proportional to the number of moles of the gas and the ideal gas constant.

The formula for the ideal gas law is:

PV = nRT

Where: - P is the pressure of the gas - V is the volume of the gas - n is the number of moles of the gas - R is the ideal gas constant (8.314 J/(mol·K)) - T is the temperature of the gas in Kelvin

To calculate the relative molar mass of a gas, we can rearrange the ideal gas law equation to solve for n:

n = PV / RT

The relative molar mass (M) of a gas is then given by:

M = m / n

Where: - m is the mass of the gas - n is the number of moles of the gas

To calculate the relative density of a gas, we can use the following formula:

Relative Density = (Molar Mass of Gas) / (Molar Mass of Hydrogen)

Let's calculate the relative molar mass and relative density for the given gases:

1. Gas with a relative density of -22: - Relative Molar Mass (M) = -22 * (Molar Mass of Hydrogen) - Relative Density = -22

2. Gas with a relative density of 8.5: - Relative Molar Mass (M) = 8.5 * (Molar Mass of Hydrogen) - Relative Density = 8.5

3. Gas with a relative density of 10: - Relative Molar Mass (M) = 10 * (Molar Mass of Hydrogen) - Relative Density = 10

4. Gas with a relative density of 19: - Relative Molar Mass (M) = 19 * (Molar Mass of Hydrogen) - Relative Density = 19

To calculate the molar mass of hydrogen, we need to know the atomic mass of hydrogen. The atomic mass of hydrogen is approximately 1.008 g/mol.

Let's calculate the relative molar mass and relative density for the given gases using the atomic mass of hydrogen:

1. Gas with a relative density of -22: - Relative Molar Mass (M) = -22 * 1.008 g/mol - Relative Density = -22

2. Gas with a relative density of 8.5: - Relative Molar Mass (M) = 8.5 * 1.008 g/mol - Relative Density = 8.5

3. Gas with a relative density of 10: - Relative Molar Mass (M) = 10 * 1.008 g/mol - Relative Density = 10

4. Gas with a relative density of 19: - Relative Molar Mass (M) = 19 * 1.008 g/mol - Relative Density = 19

Please note that the units for the relative molar mass and relative density will be in grams per mole (g/mol) and dimensionless, respectively.
