A solution of 5.00 g of acetic acid in 100. g of benzene freezes at 3.37°C. A solution of 5.00 g of acetic acid in 100. g of water freezes at −1.49°C. Find the molar mass of acetic acid from each of these experiments. What can you conclude about the state of the acetic acid molecules dissolved in each of these solvents? Recall the discussion of hydrogen bonding in Section 11.3, and propose a structure for the species in benzene solution.
