Question:medium

A gaseous mixture contains 2 moles of monatomic gas and 2 moles of diatomic gas at a temperature of 500 K. The total internal energy of the gaseous mixture is
(Atmospheric pressure = $10^5$ Pa and universal gas constant = $8.3 \, J mol^{-1} K^{-1}$)

Show Hint

Remember degrees of freedom ($f$): Monatomic = 3 (translational only). Diatomic = 5 (3 translational + 2 rotational).
