Hydrogen and oxygen are known to from two compounds. The hydrogen content in one 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 pf 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.
