    \[C{{O}_{2}}\] gas obtained by the combustion of \[12\,\,mL\] butane gas is

    A) \[3\,\,mL\]                         

    B) \[12\,\,mL\]

    C) \[24\,\,mL\]      

    D)                        \[48\,\,mL\]

    Correct Answer: D

    Solution :

    \[\underset{\begin{smallmatrix}  1\,\,mol \\  12\,\,mL \end{smallmatrix}}{\mathop{{{C}_{4}}{{H}_{10}}}}\,+\frac{13}{2}{{O}_{2}}\xrightarrow{{}}\underset{\begin{smallmatrix}  4\,\,mol \\  12\times 4=48\,\,mL \end{smallmatrix}}{\mathop{4C{{O}_{2}}}}\,+5{{H}_{2}}O\]
