Numericals on vont hoff factor| Abnormal molar mass and its numericals

The van't hoff factor can be expressed as the ratio of (i) normal molar mass to that of abnormal molar mass (ii) Observed colligative to that of calculated colligative property (iii) Total number of moles of particles after association// dissociation to that of total number of moles of particles before association//dissociation (iv) Observed molality to that of calculate molality
