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

`12.7g`

B

`15.9g`

C

`31.8g`

D

`63.5g`

Text Solution

Verified by Experts

The correct Answer is:
b
`("Weight of" H_(2))/("Ew of" H_(2))=("Weight of Cu")/(E_(w)" of Cu")`
`(0.5)/(1)=(x)/(63.5//2)`
`:.x=15.9g`
