Which concentration term clearly depends on temperature?
Answer and explanation
Correct answer: Molarity
Molarity contains the volume of the solution in its denominator, and solution volume can change when temperature changes. The moles of solute remain fixed, but expansion or contraction changes the ratio. Molality and mass percentage use masses, and mole fraction uses mole ratios, so these are not directly affected by thermal volume changes.
