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 is a simple whole number ratio, hence the given data illustrates the law of multiple proportions.
