Hydrogen and oxygen are known to form two compounds. The hydrogen content in one of these is 5.93% while in the other it is 11.2%. Show that this data illustrates the law of multiple proportions.

Explanation

In the first compound, Hydrogen `=5.93%`
Oxygen `=(100-5.93)%=94.07%`
In the second compound, Hydrogen `=11.2%`
Oxygen `=(100-11.2)%=88.8%`
In the first compound the number of parts by mass of oxygen that combine with one part by mass of
`"hydrogen"=(94.07)/(5.93)="15.86 parts"`
In the second compound the number of part by mass of oxygen that combine with one part by mass of `"hydrogen"=(88.8)/(11.2)="7.9 parts"`
The ratio of masses of oxygen that combine with fixed mass (1 part) by mass of hydrogen is 15.86 : 7.9 or 2:1. Since this ratio, hence the
