A solution has 15 percent solute by mass. What does this correctly mean?
Answer and explanation
Correct answer: 15 g solute in 100 g solution
Mass percent is calculated using the total mass of solution in the denominator: mass percent = mass of solute/mass of solution × 100. Therefore, 15% by mass means 15 g solute is present in every 100 g of solution. It does not mean 100 g solvent, 100 mL solution, or a molarity value. Option B is correct.
