Which law of chemical combination is obeyed by the above experimental data?

“When two elements combine with each other to form two or more compounds, the ratios of the masses of one element that combines with the fixed mass of the other are simple whole numbers”. This is called as Law of multiple proportion.

Ex: ${\text{N}}_{\text{2}}+{\text{\hspace{0.17em}\hspace{0.17em}O}}_2\to 2{\text{\hspace{0.17em}NO;\hspace{0.17em}\hspace{0.17em}N}}_{\text{2}}+5/2{\text{\hspace{0.17em}O}}_2\to {\text{\hspace{0.17em}N}}_{\text{2}}{\text{O}}_{\text{5}}$
