Calculate the percentage composition of the compound by weight?

A 0.24 g sample of 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. Solution : Total mass of Compound = 0.24 g (Given)Mass of boron = 0.096 g (Given)
Mass of oxygen = 0.144 g (Given)
Thus, percentage of boron by weight in the compound = 0.096 / 0.24 x 100%
= 40%
And, percentage of oxygen by weight in the compound = 0.144 / 0.24 x 100%= 60%
