Q. A metallic oxide contains $60 \%$ of the metal. Ine equivalent weight of the metal is

Some Basic Concepts of Chemistry

Solution:

Equivalent weight of a metal is the weight which combines with $8 \,g$ of oxygen.

In $100 \,g$ of metal oxide, metal $=60\, g$, oxygen $=40 \,g$

Equivalent weight of metal $=\frac{60}{40} \times 8=12$
