# Which of the following quantities is independent of the nature of gas at the same temperature?

(A) the number of molecules in equal volume (B) the kinetic energy of 1 mole (C) the kinetic energy of unit mass (D) the transnational kinetic energy of 1 mole

The number of molecules will depend on the pressure conditions. The kinetic energy depends on the molar mass and degrees of freedom.
But translational kinetic energy is $\large\frac{3}{2}$$RT$ for 1 mole for every gas and hence independent of the nature of the gas at the same temperature.
