The density of copper is 8 gm/cc. Number of coulombs required to plate an area of 10 cm x 10 cm on both sides to a thickness of `10^(-2)` cm using `CuSO_(4)` solution as electrolyte is (Atomic weight of Cu - 64g)

A

`48,250`

B

`24,125`

C

`96,500`

D

`10,000`

Text Solution

Verified by Experts

The correct Answer is:
A
`V="area"xx"thickness"=1cc`
Total volume 2cc
1cc volume = 8 gms of copper
wt of copper for 2cc = 16 gms
96500C = 32 gms of copper
32 gms of copper = 96500C
16gms = ?
