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`
`therefore ` Atomic mass of `M = 32 xx 2 = 64`
The metal nitrate formed has the formula `M(NO_(3))_(2)`
`therefore ` Molecular mass of the metal nitrate
`= 64+28+96 = 188`
