Show answer & explanation
Correct answer: B
Approach: find the amount of solute in each solution, add them, and divide by the total volume.
20% of 6 L = 0.20 × 6 = 1.2 L of solute.
60% of 4 L = 0.60 × 4 = 2.4 L of solute.
Total solute = 1.2 + 2.4 = 3.6 L. Total volume = 6 + 4 = 10 L.
Percentage of solute in the mixture = (3.6 / 10) × 100 = 36%
