Answer :

Equivalent weight of metal oxide = 52 grams

Step-by-step explanation :

Given,

20% of oxygen in oxide.

So, in 100 grams,

If 20 grams of oxygen in metal oxide, the weight of metal will be :

=> 100 - 20

=> 80 grams of metal.

Then,

.°. Mass of metal / Mass of oxygen = Equivalent weight of metal / Equivalent weight of oxygen

=> 80 g / 20 g = x / 8

=> 80 × 8 / 20 = x

.°. x = 32 grams
