Question

If the oxides of a metal contain 78.7% and
64.5% of oxygen and if the formula of
the first oxides is MO, find the formula
of other oxide, the ratio of oxygen in two
oxides is 1:3.​

Answer 1

Answer:

As the ratio of oxygen in two metal oxides is 1: 3, and one oxide is MO, the formula of the other metal oxide is MO3.
