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

48250

B

24125

C

95500

D

10000

Text Solution

Verified by Experts

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