A 600 mL solution contains 30 mL solute. What is the volume percentage?
Answer and explanation
Correct answer: 5 percent
For volume percentage, use the governing relation: volume percent = (volume of solute ÷ volume of solution) × 100. Therefore, (30 mL ÷ 600 mL) × 100 = 0.05 × 100 = 5%. Option A is correct. The millilitre units cancel because both quantities use the same unit. The value 30 mL is not a percentage, and omitting the multiplication by 100 would give only the fraction 0.05.
