    3.6 gram of oxygen is adsorbed on 1.2 g of metal powder. What volume of oxygen adsorbed per gram of the adsorbent at 1 atm and 273 K?

    A) \[0.19L{{g}^{-1}}\]                 

    B) \[1L{{g}^{-1}}\]

    C) \[2.1\text{ }L\text{ }{{g}^{-1}}\]                     

    D) None of these

    Correct Answer: C

    Solution :

    [c] Mass of \[{{O}_{2}}\]  per gram of adsorbent \[=\frac{3.6}{1.2}=3\] No. of moles of \[{{O}_{2}}\]  per gram of \[adsorbent=\frac{3}{32}\] Volume of \[{{O}_{2}}\] per gram of adsorbent \[=\frac{3}{32}\times \frac{0.0821\times 273}{1}=2.10\]
