Question

the experimental value for the molar mass of non volatile solute is twice the theoretical value what is the van't hoff factor for solute

Answer 1

Van’t Hoff factor (i) = 2.

The Van’t Hoff factor is a quantity described as the ratio between experimental and theoretical colligative properties. These properties are based on the number of particles, in this case - solute, that are found in a particular mixture.

According to the question, experimental mass is twice the theoretical mass. Hence, their ration will be. When i = 2, it is dissociative in nature, that is, the original molecule splits into two substituent molecules on dissolving in water.

Answer 2

vant Hoff factor for solute is 2
