A 200 mL solution contains 6 g solute. What is the mass-volume percentage?
Answer and explanation
Correct answer: 3 percent
Mass-volume percentage is governed by the formula (mass of solute in grams ÷ volume of solution in millilitres) × 100. Substituting the data gives (6 ÷ 200) × 100 = 3%. Hence option A is correct, and the result means 3 g of solute per 100 mL of solution. It is not a mass percentage because the denominator is volume, not the total mass of the solution.
