A 18.50 gram sample of a gas exerts a pressure of 2.40 atmospheres when held in an 7.00 liter at 25.0 °C. What is the molar mass of the gas?

I noticed you posted several similar problems that are all solved using 
PV = nRT
P = nRT/V
T = PV/(nR)
V = nRT/P
n = PV/(RT)
n = mass / (molecular weight)
I suggest you review the answered questions, and then try working with one or more of the equations above to solve the rest of the problems.
