    The volume of 1 g each of methane \[(C{{H}_{4}})\], ethane \[({{C}_{2}}{{H}_{6}})\], propane\[({{C}_{3}}{{H}_{8}})\] and butane \[({{C}_{4}}{{H}_{10}})\] was measured  at  350  K  and  1 atm. What  is  the  volume  of butane   [NCERT 1981]

    A)                 495 \[c{{m}^{3}}\]           

    B)                 600 \[c{{m}^{3}}\]

    C)                 900 \[c{{m}^{3}}\]           

    D)                 1700 \[c{{m}^{3}}\]

    Correct Answer: A

    Solution :

               \[V=\frac{nRT}{P}=\frac{m}{M}.\frac{RT}{P}=\frac{1}{58}\times \frac{0.82\times 350}{1}=0.495lit.\]                                 = 495 cm3
