In a pure compound the mass ratio A:B is 5:6 and total mass is 44 grams. What is the mass of B?

Answer and explanation

Correct answer: 24 grams

The relevant governing concept is the law of definite proportions. It states that a pure compound contains its constituent elements in a fixed mass ratio. For A:B = 5:6, the total number of ratio parts is 5 + 6 = 11. The total mass is 44 g, so one part has mass 44 ÷ 11 = 4 g. B contributes 6 parts, giving 6 × 4 = 24 g. Hence, option C is correct. Option A is the mass of A, option B is the total compound mass, and option D is not obtained from the ratio. As a check, A weighs 5 × 4 = 20 g; 20 + 24 = 44 g and 20:24 simplifies to 5:6.
