A certain current liberated 0.50 g 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

12.7 g

B

15.9 g

C

31.8 g

D

63.5 g

Text Solution

Verified by Experts

The correct Answer is:
B
`("Weight of" Cu)/("Weight of" H_2)=(Eq."weight of" Cu)/(Eq. "weight of" H)`
`("Weight of" Cu)/0.50=(63.5//2)/1` `implies`Weight of Cu=15.9 g
