alleryThe van't Hoff factor i is defined as the ratio of:
Acalculated colligative property to observed property
Bmolality of solute to molality of solvent
Cnormal molar mass to abnormal molar mass
Dabnormal molar mass to normal molar mass
Answer & Solution
Correct answer: C. normal molar mass to abnormal molar mass
1. The van't Hoff factor accounts for association or dissociation of solute.
2. It is defined as $i = $ normal molar mass / abnormal (observed) molar mass.
3. Equivalently it is observed colligative property / calculated colligative property, which is the reciprocal of option C.
