Answer and explanation
Correct answer: 20 percent
Volume percent = volume of solute/final volume of solution × 100. The acid volume is 30 mL and the final solution volume is 150 mL. Therefore, volume percent = 30/150 × 100 = 20%. Option B is correct. The water volume is not used as the denominator because the question gives the final solution volume.
