    When 3.86 A current is passed through an electrolyte for 50 min, 2.4 g of a divalent metal is deposited. The gram atomic weight of the metal (in grams) is

    A)  24                                         

    B)  12

    C)  64                                         

    D)  40

    Correct Answer: D

    Solution :

                     \[w=Zit\] or            \[w=\frac{Eq.weight}{96500}\times i\times t\] or            \[w=\frac{Atomic\,weight}{Valency\times 96500}\times i\times t\] Atomic weight \[=\frac{w\times valency\times 96500}{i\times t}\] \[=\frac{2.4\times 2\times 96500}{3.86\times 50\times 60}=40\]
