The values of observed and calculated molecular weights of silver nitrate are $92.64$ and $170$ respectively. The degree of dissociation of silver nitrate is:

One mole of a solute $\mathrm{A}$ is dissolved in a given volume of solvent. The association of the solute take place as follows:

$\mathrm{nA}\rightleftharpoons {\mathrm{A}}_{\mathrm{n}}$

If $\mathrm{\alpha }$ is the degree of association of $\mathrm{A},$ the Van 't Hoff factor is expressed as:

For a binary ideal liquid solution, the total pressure of the solution is given as:
