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