A bivalent metal has an equivalent mass of 32. The molecular mass of the metal nitrate is

A

168

B

192

C

188

D

182

Text Solution

Verified by Experts

The correct Answer is:

C

`"At. Mass of metal "="Eq. mass" xx "Valency"`
`=32xx2=6`
As metal M is bivalent, formula of its nitrate will be M `(NO_(3))_(2)`
Mol. Mass of `M(NO_(3))_(2)=64+2(14+48)`
`=64+124=188`
