Question

Explain abnormal molar mass and explain van’t Hoft factor.Explain the given question in detail.

Answer 1

Answer:

Explanation:

The Hoff factor is a measure of the solvent's impact on the colligative properties like the osmotic pressure, relative vapour pressure reduction, the elevation of the boiling point, and the depression of the freezing point. It is the proportion between the real particle concentration generated when the material is dissolved and a substance concentration as calculated from its mass. It is represented as -

i = Normal molar mass/Abnormal molar mass

A substance is said to have an abnormal molecular or molar mass when the substance's molecular mass is determined by measuring any of its colligative properties that differs from the theoretically expected value.
