A bivalent metal has an equivalent mass ...

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
Atomic mass of metal = Eq. mass `xx` valency
`=32xx2=64`
Formula of metal nitrate `= M(NO_(3))_(2)`
`:.` Molecular mass of the metal nitrate `= 64+2(14+3xx16)=188`
