What is the volume in liters that contains 50.32 g of C2H6 (ethane) gas?

Answer 1

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"#.

To determine the volume of a gas, you can use the ideal gas law equation: PV = nRT. Given the mass of ethane (C2H6), you can first calculate the number of moles (n) using the molar mass of ethane, then rearrange the equation to solve for volume (V) using the given temperature and pressure.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
