A current of 0.5 amperes is passed for 30 minutes through a voltmeter containing `CuSO_4` solution. Find the weight of Cu deposited.

A

3.18 g

B

0.318 g

C

0.296 g

D

0.150 g

Text Solution

Verified by Experts

The correct Answer is:
C
w=Zit
`Z=E/96500=(Mol.wt.//2)/96500` (for copper, E=mol. Wt/2) `theefore` `w=63.5/2xx1/96500xx0.5xx30xx60=0.296` g
