When 48250 C of electricity is passed through an aqueous solution of `NiI_(2)` (at.mass of Ni = 58.8) , the weight of nickel metal deposited be

A

7.3 gm

B

14.7 gm

C

22.0 gm

D

29.4 gm

Text Solution

Verified by Experts

The correct Answer is:
B
96500 C will deposit 1 gm equivalent i.e. `(58.8)/(2) [("At. Mass")/("valency")]` g of Nickel
`therefore` 48250 C will deposits `= (48250)/(96500) xx (58.8)/(2) = 14.7` g
