Question:

Use $\mathrm{R}=8.3 \mathrm{~J} / \mathrm{mol}-\mathrm{K}$ wherever required.

Find the average magnitude of linear momentum of a helium molecule in a sample of helium gas at $0^{\circ} \mathrm{C}$. Mass of a helium molecule $=6.64 \times 10^{-27} \mathrm{~kg}$ and Boltzmann constant $=1.38 \times 10^{-23} \mathrm{~J} / \mathrm{K}$.
