$\displaystyle 0$ g of $\displaystyle \mathrm{H}_2$ gas is adsorbed on $\displaystyle 2.5$ g of platinum powder at $\displaystyle 300$ K and $\displaystyle 1$ bar pressure. The volume of the gas adsorbed per gram of the adsorbent is \_\_\_\_ mL. (Given : $\displaystyle \mathrm{R}=0.083 \mathrm{~L} \mathrm{bar} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ )
