Apply the ideal gas law: PV= nRT, and solve for the number of moles (n). Once you have the number of moles (n), you can solve for molar mass.
Explanation:
The "trick" to solving this problem, is to convert everything to the proper units. So P ressure should be in ATM, T emperature in Kelvin, and Volume to liters. Then using algebra, n= RT/PV, solve for n.
The molar mass is grams divided by moles, so just use the mass given and the value of n you just found.
