A certain current liberates `0.5g` of hydrogen in 2 hours. How many grams of copper can be liberated by the same current flowing for the same time in a copper sulphate solution ?

A

31.8 g

B

16.0 g

C

12.7 g

D

63.5 g

Text Solution

Verified by Experts

The correct Answer is:
C
`(W_(1))/(E_(1))=(W_(2))/(E_(2))`
`(W_(Cu))/((63.5)/(2))=(0.504)/((2)/(2))`
`W_(Cu)=0.504xx63.5=31.8gm`.
