To solve the problem of determining the percentage association of benzoic acid in benzene, we will follow these steps: ### Step 1: Understand the given data - Mass of benzoic acid (solute), \( W_2 = 2 \, \text{g} \) - Mass of benzene (solvent), \( W_1 = 25 \, \text{g} \) - Depression in freezing point, \( \Delta T_f = 1.62 \, \text{K} \) - Freezing point depression constant for benzene, \( K_f = 4.9 \, \text{K kg mol}^{-1} \) ...
