The total kinetic energy of molecules of a gas at a given temperature depends on the number of gaseous molecules.

Kinetic energy of one mole of gas is $\frac{3}{2}\mathrm{RT}.$

Kinetic energy of n mole of gas is $\frac{3}{2}\mathrm{nRT}.$

Therefore, the expression becomes:

$\mathrm{K}.\mathrm{E}=\frac{3}{2}\mathrm{nRT}$

where, n = number of molecules of the gas, R = Universal gas constant, T = absolute temperature.
