Question

.024 gram of MG on burning in oxygen give 0.40 gram of MG what is the equivalent mass of mg

Answer 1

Answer:

12

Eqvalent weight of an element=atomic weight/valency

Explanation:

For Mg its atomic weight is 24 and valency is 2

Eq.wt.of Mg=24/2=12

This is an oxide method,so eq weight of metal/eq wt of oxygen =E/8

So eqvalent weight of oxygen is 16/2=8//

So E=12//
