Hey ya!

Firstly you have know the atomic mass of eah element of a compound.

For understanding let us take an example H2O.

Mass of Hydrogen = 1 , Mass of oxygen = 16

Total mass of the compound = 18

Now % of hydrogen = 2 / 18 × 100 = 11.1... %

Similarly oxygen = 16 / 18 × 100 = 88.7..%

Finally for percentage of an element In the compound =


[ Mass Of The Element / Mass Of The Compound ]× 100.
