Colligative
properties depend on the amount of solute dissolved in a solvent. These set of
properties do not depend on the type of species present. These properties
include freezing point depression, boiling point elevation, osmotic pressure
and vapor pressure lowering. The correct answer is the last option. The solution which has the highest amount of solute or the 2.0 m NaCl solution will have lower freezing point than the other given choices.
