    The empirical formula and molecular mass of a compound are \[C{{H}_{2}}O\] and 180 g respectively what will be the molecular formula of the compound?

    A)  \[{{C}_{9}}{{H}_{18}}{{O}_{9}}\]               

    B)  \[C{{H}_{2}}O\]

    C)  \[{{C}_{6}}{{H}_{12}}{{O}_{6}}\]         

    D)         \[{{C}_{2}}{{H}_{4}}{{O}_{2}}\]

    Correct Answer: C

    Solution :

     \[n=\frac{180}{MolecularmassofC{{H}_{2}}O}=\frac{180}{30}\]\[n=6\]
