When $1\cdot90\text{ g}$ of benzoic acid is dissolved in $26\text{ g}$ of benzene, it causes a depression in freezing point by $1\cdot60\text{ K}$. The molal depression constant for benzene is $4\cdot8\text{ K kg mol}^{-1}$ and the molecular mass of benzoic acid is $122\text{ g mol}^{-1}$.
Calculate the degree of association of benzoic acid if it forms dimer in solution.
