Question

Solution

Correct option is

MO3

Oxide I                   Oxide II

Metal, M     50%                      40%

Oxygen, O  50%                      60%

As first oxide is

Let atomic mass of M = x

or              0.5 x + 16 = 32

0.5 x = 16

x = 32

At. mass of metal M = 32

Let formula of second oxide is

2.5 = 1 + 0.25 n

Therefore, formula of second oxide
