Which option has all relations correct?

Answer and explanation

Correct answer: Molarity = moles/litre solution; molality = moles/kg solvent

Molarity is moles of solute per litre of solution, whereas molality is moles of solute per kilogram of solvent. These denominators are the key distinction. Mole fraction is a ratio of moles, mass percent uses masses, and volume percent uses volumes; therefore the mixed definitions in the other options are incorrect.
