Answer 2

Given:

Moles of gas = 1

To find:

Translational kinetic energy of the gas molecule for one mole of the gas.

Solution:

As we know that, The kinetic energy KE of a gas per molecule:

KE/m = 3/2 KbT

Also, n = m/N

where n = number of moles

N = Avogadro's number

m = number of molecules

So, KE/ nm = 3/2 KbT

Therefore the kinetic energy per molecule per mole = 3/2 KbT.
