In order to calculate the volume in liters that contains "50.32g" of ethane gas, you must first identify the molar volume of a gas, and the molar mass of ethane. Then you will use dimensional analysis to

Known/Given:
molar volume of any gas = "22.414L/mol" at STP.
molar mass of ethane = "C"_"2""H"_6", = "30.07g/mol":
"["("2" x "12.011g/mol") + ("6" x "1.008g/mol")"]"

Solution:
"50.32g" "C"_"2""H"_6" x "22.414L"/"1mol" x "1 mol"/"30.07g" = "37.51"L

At STP, the volume in liters occupied by "50.32g" ethane gas is "37.51L".
