Sometimes the molecular mass determined from colligative properties of solutions, show abnormal values. Explain?

Solution

Collegative properties of solution are the properties which depend upon the number of particles present in the solution. When the solute does not undergo any chemical/physical change, the molecular mass of the solute as obtained from the colligative properties is equal to its stoichiometric value.

Therefore in many cases where the solute associate or dissociate in solution certain abnormal values of colligative properties are obtained the value of molecule masses calculated based on colligative properties in such cases will also be abnormal.
