A tank used for filling helium balloons has a volume of 0.300 m3 and contains 2.00 mol of helium gas at 20.

A tank used for filling helium balloons has a volume of 0.300 m3 and contains 2.00 mol
of helium gas at 20.0 0C. Assuming that the helium behaves like an ideal gas, (a) what is
the total translational kinetic energy of the molecules of the gas? (b) what is the average
kinetic energy per molecule?


This is for part B. I am trying to find kB for the equation: 3/2kBT. But I can't figure out how they found kB....

kB = R/NA


I know that kB = 1.38x10^-23
and R = 8.31
What is my NA??
