the ratio of average translatory kinetic energy of he gas molecules to oxygen gas molecules is

Average kinetic energy of the gas molecule =
 = Boltzmann constant =
T = temperature of the gas in Kelvins
Average translational kinetic energy of the oxygen gas molecule at T:
..(1)
Average translational kinetic energy of the helium gas molecule at T:
...)2)
Dividing 1 and 2

The ratio of average translatory kinetic energy of he gas molecules to o2 gas molecules is 1:1.

 

Hope it helps
