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.
Mass of boron = 0.096 g (Given)
Mass of oxygen = 0.144 g (Given)
Mass of sample = 0.24 g (Given)
"Thus, percentage of boron by weight in the compound "=0.096/0.24xx100% = 40%
"percentage of oxygen by weight in the compound "=0.144/0.24xx100% = 60%
