A 0.24 g sample of a compound of oxygen and boron was found by analysis to contain 0.096 g of boron and 0.144 g of oxygen. Calculate the percentage composition of the compound by weight.
Step 1:-Percentage composition of the boron
Percentage composition of boron =
=
=
Step 2:- Percentage composition of the oxygen
Percentage composition of oxygen =
=
=
Thus, the percentage composition of the compound by weight is of boron and of oxygen.
