Analysis of one of the nitrogen oxides showed that the mass fractions of nitrogen and oxygen

Analysis of one of the nitrogen oxides showed that the mass fractions of nitrogen and oxygen in it are equal to 36.84 and 63.16%, respectively. determine the simplest oxide formula

Let’s designate the unknown nitric oxide as NхOy.
Let’s compose the ratio of the percentage to molar mass.
NxOy = 36.84 / 14: 63.16 / 16 = 2.63: 3.95.
NxOy = 1: 1.5.
Nitrogen and oxygen are in a ratio of 1: 1.5. Let’s round up to the whole value by multiplying by 2.
NxOy = 2: 3.
We get nitric oxide (III) with the corresponding formula – N2O3.
