$2.0 \mathrm{g}$ of ${\mathrm{H}}_{2 }\mathrm{gas}$ is adsorbed on $2.5 \mathrm{g}$ of platinum powder at $300 \mathrm{K}$ and $1$ bar pressure. The volume of the gas adsorbed per gram of the adsorbent is $\mathrm{mL}$

(Given : $\mathrm{R}=0.083 \mathrm{L}$ bar ${\mathrm{K}}^{-1}{ \mathrm{mol}}^{-1}$)

Match List - I with List - II.

Choose the correct answer from the options given below
