114. Solving a chemistry problem
A certain amount of a substance dissolved in 100 g of benzene lowers its freezing point by 1.28 C. The same amount of a substance,
dissolved in 100 g of water, lowers its freezing point by 1.395 C. The substance has a normal molar mass in benzene, and in water
completely dissociated. By how many ions does a substance dissociate in an aqueous solution? The cryoscopic constants for benzene and water are
5.12 and 1.86 K*kg*mol–1.
