1.22 g of an organic acid is separately dissolved in 100 g of benzene (K_b = 2.6 K kg mol^$$-$$1) and 100 g of acetone (K_b = 1.7 K kg mol^$$-$$1). 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$$^\circ$$C. The increase in boiling point of solution in benzene in $$^\circ$$C is x $$\times$$ 10^$$-$$2. The value of x is ______________. (Nearest integer) [Atomic mass : C = 12.0, H = 1.0, O =16.0]
