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.
