AMoles of solute per kilogram of solvent
BMoles of solute per litre of solution
CMass of solute per mass of solution × 100
DGrams of solute per litre of solution
Answer & Solution
Correct answer: A. Moles of solute per kilogram of solvent
**Molality (m) = moles of solute / kg of solvent**.
(Molarity uses volume of solution; mass-% uses mass of solution.)
