    When 9.65 coulombs of electricity is passed through a solution of silver nitrate (atomic weight of \[Ag=107.87\] taking as 108) the amount of silver deposited is [EAMCET 1992; KCET 2000]

    A)                 10.8 mg               

    B)                 5.4 mg

    D)                 21.2 mg

    Correct Answer: A

    Solution :

                    \[{{W}_{Ag}}=\frac{{{E}_{Ag}}\times Q}{96500}=\frac{108\times 9.65}{96500}\] \[=1.08\times {{10}^{-2}}gm=10.8\,mg\]
