The average kinetic energy per mole of a gas is equal to 2/3 RT where T is the absolute temperature.
When the temperature is same, the average kinetic energy per mole will be same for hydrogen, oxygen and methane as the average kinetic energy per mole is independent of its molar mass.
topper answer .. I hope it's helpful for you..
