`2.0g` of a metallic carbonate on decomposition gave `1.5g` of metallic oxide. The equivalent mass of metal is

A

58

B

29

C

5.8

D

2.9

Text Solution

Verified by Experts

The correct Answer is:
A
`("weight of metal carbonate")/("weight of metallic oxide") = ("eq. mass of metal + eql. Mass of" CO_(3)^(2-))/("eq mass of metal + eq mass of" O^(2-))`
