A solute A dimerizes in water. The boiling point of a $\displaystyle 2$ molal solution of A is $\displaystyle 100.52$°C. The percentage association of A is \_\_\_\_. (Round off to the Nearest Integer).
[Use : $\displaystyle \mathrm{K}_{\mathrm{b}}$ for water $\displaystyle =0.52 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$
$$\text { Boiling point of water } \left.=100^{\circ} \mathrm{C}\right]
$$
