Question

If observed molar mass of a solute is more than calculated molar mass, then the solute undergoes - - - - - in the solvent​

Answer 1

yes the solute has  more mass then solvent

Answer 2

If observed molar mass of solute is more than calculated then it undergo association

Explanation:

• In association solute show their observed molar mass more than calculated molar mass.

• In association its value of i which is van't- Hoff factor is less than 1

• In association the value of property like elevation in B.P and depression in freezing are lower than actual.

• In association the particle get associate and in dissociation the particles gets dissociate into no. of particle.

• It show i value more than one and also its observed molar mass are less than actual
