When is density required to convert between mass percent and molarity?
Answer and explanation
Correct answer: When solution volume is needed
Mass percent gives the mass of solute relative to the mass of solution, whereas molarity requires moles per litre of solution. Density supplies the missing connection between solution mass and solution volume. Without density, a numerical mass-to-volume conversion generally cannot be completed.
