Molecules of benzoic acid (C_(6)H_(5)COOH) dimerise in benzene. ‘w’ g of the acid dissolved in 30g of benzene shows a depression in freezing point equal to 2K. If the percentage association of the acid to form dimer in the solution is 80, then w is : (Given that K_(f)=5K Kg "mol"^(-1) Molar mass of benzoic acid =122 g "mol"^(-1) )

Freezing Point Depression: when 15.0 grams of ethyl alcohol (C_(2)H_(5)OH) is dissolved in 750 grams of formic acid, the freezing point of the solution is 7.20^(@)C . The freezing point of pure formic acid is 8.40^(@)C Evalulate K_(f) for formic acid. Strategy: First calculate the molality and the depression of the freezing point. Then solve the equation DeltaT_(f)=K_(f)m for K_(f) by substituting values for m and DeltaT_(f) .
