Question

0.24 G sample of compound of Oxygen and Boron was found by analysis to contain 0.096 gram of Boron and 0.144 gram of oxygen. Calculate the percent composition of compound of weight

Answer 1



% of boron  = 0.096/0.24 X 100 = 40%

% of oxygen = 0.144/0.24 X 100 = 60%

☺ Hello mate__ ❤

◾◾here is your answer.

Mass of boron = 0.096g

Mass of oxygen = 0.144g

Mass of sample = 0.24g

Thus, percentage of boron by weight in the compound =( 0.0960 × 100)/0.24 = 40%

Thus, percentage of oxygen by weight in the compound = (0.144× 100)/ 0.24 = 60 %
