avg kinetic energy of ideal gas is 3/2 kT. k is Boltzman constant. T is in kelvin. This give you the avg KE per molecule. Multiply that by Avogadro's number x 12.
One mole (mol) of any substance consists of 6.022 x 10²³ molecules
(Avogadro's number). What is the translational kinetic energy of 12.00mol of
an ideal gas at 290.0K?
