1.22 g of an organic acid is separately dissolved in 100 g of benzene $\left(\mathrm{K}_{\mathrm{b}}=2.6 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}\right)$ and 100 g of acetone $\left(\mathrm{K}_{\mathrm{b}}=1.7 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}\right)$. 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 $0.17^{\circ} \mathrm{C}$.
The increase in boiling point of solution in benzene in ${ }^{\circ} \mathrm{C}$ is $\mathrm{x} \times 10^{-2}$. The value of x is $\_\_\_\_$ (Nearest integer)
