We can use the elevation of boiling point, depression of freezing point to calculate the molar masses of the solute. But that gives you a weird answer at times. Why is that? We will explore this using the concept of the van 't Hoff factor that accounts for association or dissociation of the solute and causes abnormal molar masses.
