8 g solute is used to prepare 400 mL solution. What is the mass-volume percentage?
Advertisement
Answer and explanation
Correct answer: 2%
Mass-volume percentage means grams of solute present in 100 mL of solution: (mass in g/volume in mL) × 100. Here, (8/400) × 100 = 2. Therefore the solution is 2% (m/V), and option B is correct. This expression deliberately uses grams and millilitres; converting only the volume to litres would require corresponding unit care.
