Case: Read the paragraph and answer the following questions

      Colligative properties are not dependent on the chemical nature of the solution’s components. Thus, colligative properties can be linked to several quantities that express the concentration of a solution, such as molarity, normality, and molality. Boiling point elevation, freezing point depression, Relative lowering of vapour pressure and Osmotic pressure are the major colligative properties exhibited by solutions. In 1880 van’t Hoff introduced a factor i, known as the van’t Hoff factor, to account for the extent of dissociation or association.

Which of the following is inversely proportional to colligative properties?

Molar mass

Colligative properties ∝ Number of moles of solute

Number of moles = (Given mass / Molar mass)

Therefore colligative properties are inversely proportional to Molar mass.
