Someone can help me please?

A gas sample weighing 0.528 g is collected in a flask having a volume of 126 mL. At 75 degrees celcius the pressure of the gas is 75 torr. The molecular mass of the gas is closest to which one of the following?

Use PV = nRT
Calculate n.
Then n = grams/molar mass. Calculate molar mass.
You didn't post any possibilities.
