Answer:
21.13 g/eq
Explanation:
1.40g of a metal on heating in air forms 1.93g of metal oxide.
Thus, the amount of O present in 1.93g of metal oxide is 1.93g- 1.40g=0.53g
The equivalent weight of metal is the mass of metal that combines with 8 parts by mass of oxygen.
It is equal to
=1.40/0.53 × 8
=21.13g/eq
Hence, the equivalent weight of metal is 21.13g/equivalent.
