Question

Hydrogen and oxygen combine to form two compounds the hydrogen content in one is 5.93 % and in other it is 11.2% show that this explain law of multiple proportion

Answer 1

The law of multiple proportion states that the masses of one element which combine with a fixed mass of the second element are in a ratio of whole numbers.
The two compounds of H and O have a hydrogen content of 5.93% and 11.2%.
Compound 1
Hydrogen mass = 5.93%
Oxygen mass = 100-5.93 = 94.07%
The number of parts of O that combine with H = 94.07/5.93 = 15.86 parts
Compound 2
Hydrogen mass = 11.2%
Oxygen mass = 100- 11.2 = 88.8%
The number of parts of O that combine with H = 88.8/11.2 = 7.9 parts
Ratio of the masses of O that combine with fixed mass of H = 15.86: 7.9 = 2:1
This is a whole number ratio as stated by Law of multiple proportion.
