2.0 g of $\mathrm{H_2}$ gas is adsorbed on 2.5 g of platinum powder at 300 K and 1 bar pressure. The volume of the gas adsorbed per gram of the adsorbent is ______ mL.

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

Your answer

Answer and worked solution

Official answer: 9960

Volume of 1 mol $\mathrm{H_2}$ at 300 K and 1 bar: $V=0.083\times300=24.9$ L $=24900$ mL.

Per gram of Pt. $\dfrac{24900}{2.5}=9960$ mL.

Answer: 9960
