Solute A associates in water. When $0.7 \mathrm{g}$ of solute $\mathrm{A}$ is dissolved in $42.0 \mathrm{g}$ of water, it depresses the freezing point by $0.2 °\mathrm{C}$. The percentage association of solute $\mathrm{A}$ in water, is

[Given: Molar mass of $\mathrm{A}=93 \mathrm{g}{ \mathrm{mol}}^{-1}$. Molal depression constant of water is $1.86 \mathrm{K} \mathrm{kg}{ \mathrm{mol}}^{-1}$]
