 Homework Statement:
 The pressure of a 0.02 m3 monoatomic gas in a container is 2 atm. The mass of each atom is 3.351 x 10^23 g. Calculate the average translational kinetic energy of the gas.
 Relevant Equations:

Ktr = (3/2) (R/NA) T = (3/2)kT
U = NKtr = (3/2) nRT = (3/2)NkT
If this question asked for internal energy, then it is a straightforward thing, just use the formula U = (3/2) nRT = (3/2) PV. But the question specifically asked for average translational kinetic energy which I'm stuck with the value of T to plug in into the formula as the question only give us P and V. So no value for n and T.
