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?
Using Figure 3.1, determine a. the number of grams of CuSO45H2O that will dissolve in 100g of H2O at 100C. gCuSO45H2O b. the number of grams of water required to dissolve 4.0g of CuSO45H2O at 100C. Hint: your answer to Problem 1a gives you the needed conversion factor for g CuSO45H2O to gH2O. gH2O c. the number of grams of water required to dissolve 18gKNO3 at 100C. gH2O d. the number of grams of water required to dissolve a mixture containing 18gKNO3 and 4.0g CuSO45H2O, assuming that the solubility of one substance is not affected by the presence of another. gH2O
