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
Given, equivalent mass of bivalent metal, `M^(2+)=32`
`:.` Atomic mass of `M=32xx2=64`
The metal nitrate formed has the formula `M(NO_(3))_(2)`
`:.` Molecular mass of the metal nitrate `=64+28+96=188`.
