The solubility of acetanilide in hot water is 5.5 g/100 mL at 100 °C and its solubility in cold water is 0.53 g/100 mL at 0 °C. a) Calculate the volume of water necessary to dissolve 500.0 mg of acetanilide at 100°C. This is the theoretical ideal volume of water to recrystallize 500.0 mg acetanilide. M1V1=M2V2 -> V2=M1V1/M2 = (5.5g)(100ml)/(0.5g)=1100ml. b) Assume that the solution from part a was cooled to 0°C. Calculate the mass of acetanilide that would remain dissolved in the chilled water calculated in part a. This mass is the acetanilide that could not be recovered from the chilled solution. c) Calculate the mass of acetanilide that could be recovered under these ideal conditions. This is 500.0 mg - (mass calculated in part b).

Patients undergoing an upper gastrointestinal tract laboratory test are typically given an X-ray contrast agent that aids with the radiologic imaging of the anatomy. One such contrast agent is sodium diatrizoate, a nonvolatile water-soluble compound. A 0.378-m solution is prepared by dissolving 38.4 g sodium diatrizoate (NaDTZ) in.l.60 102 mL water at 3 1.2C (the density of water at 31.2C is 0.995 g/cm3). What is the molar mass of sodium diatrizoate? What is the vapor pressure of this solution if the vapor pressure of pure water at 31.2C is 34.1 torr?
