  • question_answer
    The volume occupied by 9.0 g of nitrogen gas at 300 K and 750 mm Hg pressure is:

    A) 5.854                                    

    B) 6.7432

    C) 8.8462                                  

    D) 8.0125

    Correct Answer: D

    Solution :

    \[PV=\frac{w}{M}RT\] Let V be the volume occupied \[P=750\,mm=\frac{750}{760}\,atm\] \[V=?\] \[w=9\,g,\,T=300\,K\] \[V=\frac{wRT}{MP}=\frac{9\times 0.082\times 300\times 760}{28\times 750}=8.0125\,L\]
