When 3 . 86 A current is passed through an electrolyte for 50 min , 2.4 g of divalent metal is deposited .The gram atomic weight of the metal is (in gram )

A

24

B

12

C

64

D

40

Text Solution

Verified by Experts

The correct Answer is:
D
`w=Z it`
or `w=("Eq . weight")/(96500)xxixxt`
or `w=("Atomic weight")/("Valency"xx96500)xxixxt`
Atomic weight `=(wxx"valency"xx96500)/(ixxt)`
`=(2.4xx2xx96500)/(3.86xx50xx60)`
