Mass of boron as given = 0.096 g
Mass of oxygen as given = 0.144 g
Mass of sample as given = 0.24 g
Percentage of boron by weight in the compound = (0.096 ÷ 0.24 ) x 100 = 40%
Percentage of oxygen by weight in the compound = (0.144 ÷ 0.24) x 100 = 60%
Mass of oxygen as given = 0.144 g
Mass of sample as given = 0.24 g
Percentage of boron by weight in the compound = (0.096 ÷ 0.24 ) x 100 = 40%
Percentage of oxygen by weight in the compound = (0.144 ÷ 0.24) x 100 = 60%
