    The molar volume, symbol Vm, is the volume occupied by one mole of a substance at a given temperature and pressure. It is equal to the molar mass divided by the mass density. Therefore, we calculate as follows:

    Vm (CO2) = 44.01 / 1.56 = 28.21 cm^3 / mol

    Vm (NH3) = 17.03 / 0.84 = 20.27 cm^3 / mol
