Question

The oxide of metal has 32% oxygen . its equivalent weight of metal would be

Answer 1

32 % O2 :

In 100 grams , we have 32 grams of O2

100 - 32 = 68 grams of metal  

Then ,  

Mass of metal / mass of O2 = Eq. wt. of metal / Eq. wt. of O2

68 / 32 = x / 8

(68×8) / 32 = x

x = 12g

Answer 2
