Q. The substance A when dissolved in solvent B shows the molecular mass corresponding to $A_3$. The vant Hoff factor will be

Solutions

Solution:

Van't Hoff factor.
$ i = \frac{Normal mol, mass}{Observed mol. mass }$
As the solute associates in solution, and gives mass
$A_3 \, \therefore \, i = \frac{A}{3A} = 1/3$
