    Percentage of Se (atomic mass = 78.4) in per- oxidase anhydrase enzyme is 0.5% by mass, then minimum molecular mass of peroxidase anhydrase enzyme is:

    A) \[1.576\times {{10}^{4}}\]                   

    B) \[1.576\times {{10}^{3}}\]

    C)  15.76              

    D) \[21.36\times {{10}^{4}}\]

    Correct Answer: A

    Solution :

     The enzyme must contain at least one atom of Se \[\because \] 0.5 g enzyme, molar mass = 100 \[\therefore \]78.4g enzyme, molar mass \[=\frac{100\times 78.4}{0.5}\] \[=1.576\times {{10}^{4}}\]
