Derive an equation relating molar mass of an ideal gas with its density.

What is an ideal gas?

Give the relation between molar mass of a gas (m) and its density (d). How are the densities of O_(2(g)) and CH_(4(g)) related, if they are kept at the same temperature and pressure?

Distinguish between real gas and ideal gas.

Derive the ideal gas equation.

Give the relation between density and molar mass of a gaseousl substance.

The absolute temperature of an ideal gas

Write the general equation which relates the different variables of a gas used to describe the state of any ideal gas.

Equal volumes of two gases A and B diffuse through a porous pot in 20 and 10 seconds respectively. If the molar mass of the gas A is 80. Find the molar mass of the gas B.
