Question
Cyclohexanol, C H,,OH, is sometimes used as the solvent in molecular weight determinations
by freezing-point depression. If 0.253 g of benzoic acid, C H COOH, dissolved in 12.45 g of
cyclohexanol lowered the freezing-point of pure cyclohexanol by 6.55°C, what is the molal
freezing-point constant, Ke, of this solvent?
