Question

Two oxides of a metal contain 30 and 27.6%
of oxygen. If formula of the first
oxide is M₂O3, find that of the second oxide. ​

Answer 1

Answer:

If the formula of the first oxide is X3O4,that of the second will be: 1)XO 2)XO2. 3)X2O5 4)X2O3.

Answer 2

Answer:

X³O⁴

Explanation:

1. For 1st oxide

Let mass of oxygen =30

mass of metal = 100-30 =70

2. For 2nd oxide

Mass of oxygen = 27.6

mass of metal = 100-27.6 = 72.4
