    The molar volume is the volume of 1 mol and it is calculated as:

    molar Volume = Voumen / number of moles = V / n

    Now use the formula pV = nRT, and molar volume = V / n

    => molar volumen = V / n = RT / p

    => V / n = 0.0821 atm*l / K*mol * (21.5 + 273.15) K / 1.00 atm

    => V/n = 24.19 l / mol

    Answer: 24.19 l / mol
