4g of copper was dissolved in conc. Nitric acid. The copper nitrate so obtained on strong heating gave 5 g of its oxide. The equivalent weight of copper is

A

`23`

B

`32`

C

`12`

D

`20`

Text Solution

Verified by Experts

The correct Answer is:
B
4g of copper gives 5 g of its oxide
`:.` 4 g of copper combines with 1 g of oxygen
`:.` Mass of copper that combines with 8g of oxygen `8xx4=32`
`:.` Eq. mass of copper = 32
