$\displaystyle 22$ g of an organic acid is separately dissolved in $\displaystyle 100$ g of benzene $\displaystyle \left(\mathrm{K}_{\mathrm{b}}=2.6 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}\right)$ and $\displaystyle 100$ g of acetone $\displaystyle \left(\mathrm{K}_{\mathrm{b}}=1.7 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}\right)$. The acid is known to dimerize in benzene but remain as a monomer in acetone. The boiling point of the solution in acetone increases by $\displaystyle 0.17^{\circ} \mathrm{C}$. The increase in boiling point of solution in benzene in $\displaystyle { }^{\circ} \mathrm{C}$ is $\displaystyle x \times 10^{-2}$. The value of $\displaystyle x$ is \_\_\_\_.
