Molar mass of a gas

Molar mass is the mass (in atomic mass units) of one mole of a substance. One atomic mass unit (u) is equal to 1/12 the mass of one atom of carbon-12. Thus, the molecular weight of a molecule is the total number of protons and neutrons in all the atoms in that molecule.

Molar Mass of a Gas = ( V * 0.0821 * ( G / T ) * P )

    V -> Volume
    G -> Mass of Gas
    T -> Temperature
    P -> Pressure
