Question

Van’t Hoff factor i is given by the expression _____________.

Answer 1

(i) i = Normal molar mass/Abnormal Molar mass

(iii) i = Observed colligative property/Calculated colligative property

Answer 2

Answer:

The correct answer to this question is the Actual number of particles/ Expected number of particles, i = Observed colligative property/calculated colligative property.

Explanation:

Given - Van’t Hoff factor.

To Find - Fill in the blanks.

The influence of a solute on various colligative properties of solutions is measured by the Vant Hoff factor.

i =  calculated or Normal colligative property  /  Observed colligative property

​i = Actual number of particles / Expected number of particles

So, the expression is i = the Actual number of particles/ Expected number of particles.

i = Observed colligative property/calculated colligative property

The number of ions formed when an ionic substance dissociates is known as the van't Hoff factor. For a non-ionizing molecule, the van't Hoff factor is 1. For materials that are soluble in non-polar solvents, the vant Hoff factor is used.
