    The percentage of Se in peroxidase anhydrous enzyme is 0.5% by weight (atomic weight = 78.4). Then minimum molecular weight of peroxidase anhydrous enzyme is

    A) \[15.68\]           

    B) \[1.568\times {{10}^{3}}\]

    C) \[1.568\times {{10}^{4}}\]       

    D) \[3.136\times {{10}^{4}}\]

    Correct Answer: C

    Solution :

    \[0.5\,g\,Se\to 100\,g\]peroxidase anhydrous enzyme \[78.4\,g\,Se\to \frac{100\times 78.4}{0.5}=1.568\times {{10}^{4}}\] Minimum molecular weight \[\to \]molecule at least contain one selenium.
