Calculate the mass?

Container "1" holds N2 gas with a mass of 80.1 g and is 2.6 times the volume of container "2" which holds argon (Ar) gas at the exact same temperature and pressure. What is the mass of the Ar (in g) within container "2"?

    moles N2 = 80.1 / 28.01 = 2.86 mol N2

    Moles Ar = 2.86 / 2.6 = 1.10 mol Ar

    Mass Ar = 1.10 mol  X 39.95 g/mol = 43.9 g Ar
