Question

A metal oxide contains 60% metal.the equivalent weight of metal is :-

Answer 1

60% metal means oxide is 40%
so, 100g of metaloxide contains 60g metal and 40g oxygen
therefore, equivalent weight of metal is=mass of metal x 8/mass of oxygen = (60/40)x 8=12

Answer 2

≡100g of metaloxide contains 60g metal and 40g oxygen
∵ equivalent weight of metal is=mass of metal x 8/mass of oxygen = (60/40)x 8=12
