Five 22.4 l containers each hold a different gas at stp. the container holding which gas would have the greatest mass, in grams?

Since at STP, the molar volume is 22.4 L, all of these containers have one mole of gas. The one with the highest atomic or molecular weight is the heaviest: : A) H2 - 2 g/mole B) N2 - 28 g/mole C) O2 - 32 g/mole D) CO2 - 44 g/mole E)He - 4 g/mole Ans will CO2 - 44 g/mole with the highest atomic or molecular weight is the heaviest.
