106. Solving a chemistry problem

420. A solution containing 1.632vg of trichloroacetic acid CCl3COOH and 100g of benzene C6H6 solidifies at a temperature 0.350 K below the freezing point of pure C6H6. Determine the molar mass of the solute and compare it with the molar mass of CCl3COOH. Conclude whether there is a dissociation or association of CCl3COOH in benzene. The cryoscopic constant of C6H6 is 5.12 K kg*.
