4. Since the freezing point of a solution depends on the relative number of particles, what would you calculate to be the freezing point of 0.1m solutions in water of (a) NaCl, (b) BaCl2 ? Assume the salts are 100% ionized in solution. (Compare your answers with the actual respective freezing points: 0.348C and 0.470C.) 3. Cyclohexanol, C6H11OH, is sometimes used as the solvent in molecular weight determinations by freezing-point depression. If 0.253g of benzoic acid, C6H5COOH, dissolved in 12.45g of cyclohexanol, lowered the freezing-point of pure cyclohexanol by 6.55C, what is the molal freezing-point constant of this solvent
