An experiment shows that a 114 mL gas sample has a mass of 0.167 g at a pressure of 721 mm Hg and a temperature of 32C. What is the molar mass of the gas?


so im suppose to find the molar mass but i thought that was the same as the g just converting it..?

im using the equation

pv=nrt and when i plug in the numbers there is no variable left to find so what am i finding?
