6 g solute is dissolved in 94 g solvent. What is the mass percentage?
Answer and explanation
Correct answer: 6%
The governing concept is mass percentage: mass percentage = (mass of solute ÷ mass of solution) × 100. The total solution mass is 6 + 94 = 100 g, so the percentage is (6 ÷ 100) × 100 = 6%. Therefore, option A is correct. Option C gives the solvent percentage, while option B incorrectly uses only the solvent mass as the denominator; option D does not follow the required formula.
