He is the lightest noble gas component of air, and Xe is the heaviest. Perform the following calculations, using R=8.314J/(molXK)and M in kg/mol.
1. Find the average kinetic energy per mole of He and Xe at 30 degrees C.
2. Find the average kinetic energy per molecule of He at 30 degrees C.

Isn't the average KE = 3/2 RT?
Divide by Avogadro's number to fine per molecule.
