How much metal will be deposited when a ...

How much metal will be deposited when a current of 12 ampere with 75% efficiency is passed through the cell for 3 h? (Given: Z= `4xx10^(-4)` )

A

32.4 g

B

38.8 g

C

36.0 g

D

22.4 g

Text Solution

Verified by Experts

The correct Answer is:
B
W= Z x I x t
`=4zz10^(-4) xx 12 xx 75/100 xx 3 xx 3600` =38.8 g
