Nitrogen and oxygen from two compounds. The nitrogen content of one of these is `30.43%` and the other is `46.53%`. Show that the data is in agreement with the law of multiple proportions.

Explanation

Comosition of compound - I `N =30.43%, " " O=(100-30.43)=69.57%`
Composition of compound -II `N=46.53%," "O=(100-46.53)=53.47%`
Mass of oxygen combining with 1 g of nitrogen in compound -II `=(69.57"/"30.43)=2.286 g`
Mass of oxygen combining with 1 g of nitrogen in compound - II `=(53.47"/"46.53)=1.149 g`
Ratio of masses of oxygen in the two compounds `=2.286: 1.149=2:1`
This is a simple ratio and hence illustrates the law.
