Which option gives an incorrect denominator for molality?
Answer and explanation
Correct answer: Volume of solution in litres
Molality is defined as moles of solute divided by the mass of solvent in kilograms. Therefore, the solvent-mass descriptions in B, C, and D are appropriate, with C understood as the mass of solvent used. The volume of the complete solution in litres is the denominator for molarity, not molality, so A is the incorrect choice.
