Which option gives an incorrect denominator for molarity?
Answer and explanation
Correct answer: Mass of solvent in kilograms
Molarity is moles of solute per litre of solution, so its denominator is the final solution volume. Mass of solvent in kilograms is the denominator for molality, not molarity. The final or total prepared solution volume is appropriate because it includes the volume after dissolving and making up the solution.
