Molality m is defined as:
AMass of solute per total mass
BMole fraction
CMoles solute per litre of solution
DMoles solute per kilogram of SOLVENT
Answer & Solution
Correct answer: D. Moles solute per kilogram of SOLVENT
Molality (m) = moles of solute / kg of solvent. Used for colligative property calculations because, unlike molarity, it does not depend on temperature.
