Chemistry calculation problem with volume

1.000 moles of Xe gas has a mass of 131.3g. what is the volume of 200.0g of xenon gas at STP??

find moles
200.0g of xenon times (1 mol Xe / 131.3 grams ) = 1.5232 moles of Xe

since 1 mole os gas occupies 22.4 Litres at STP:
(1.5232 moles of Xe) (22.4 L / mol) = 34.1 Litres
