Question

Quizplus · Accepted Answer

To find the percentage by mass of chlorine in Lindane (C6H6Cl6), calculate the molar mass of the compound and the total mass of chlorine. The molar mass of Lindane is approximately 290.83 g/mol (C: 12.01*6 + H: 1.01*6 + Cl: 35.45*6). The mass of chlorine is 35.45*6 = 212.7 g. The percentage by mass of chlorine is (212.7/290.83)*100% ≈ 73.1%.
