Question

Equivalent mass of a metal is 12 g/mol. Hence, equivalent mass of its oxide is

Answer 1

eq. mass of oxygen is 8g/mol so eq.mass of metal oxide is 12+8=20g/mol(since one equiv of metal reacts with one equiv of oxygen)

Answer 2

Answer: 20 gram

Explanation:

Equivalent mass of a metal is defined as the mass which combines with 8 gram of oxygen or 35.5 grams of chlorine or 1 gram of hydrogen.

Equivalent mass of oxygen (O) =$\frac{\text {Molecular mass}}{Valency}=\frac{16}{2}=8$

Given: Equivalent mass of metal = 12 g

Equivalent mass of Oxygen = 8

Thus Equivalent Mass of metal Oxide = equivalent mass of metal + equivalent mass of oxygen = 12 +8= 20 g

Thus equivalent mass of metal oxide is 20 gram.
