Question

Explain the term Abnormal molecular masses.

Answer 1

Abnormal Molecular Masses.Molecular masses can be calculated by measuring any of the colligative properties. The relation between colligative properties and molecular mass of the solute is based on following assumptions. (1) The solution is dilute, so that Raoult's law is obeyed.

Answer 2

Answer:

In chemistry, when the molar masses are calculated and if they are higher or lower than the expected value are known as abnormal molar masses. The name in itself has abnormal in it which suggests the abnormality of how the molar masses are being calculated, using the Van't Hoff factor.
