A flask contains Hydrogen and Argon in the ratio $\displaystyle 2$:$\displaystyle 1$ by mass. The temperature of the mixture is $\displaystyle 30^{\circ} \mathrm{C}$. The ratio of average kinetic energy per molecule of the two gases (K argon/K hydrogen) is :
(Given: Atomic Weight of $\displaystyle \mathrm{Ar}=39.9$ )
Official answer
From NTA’s final answer key for this paper.
