Patients undergoing an upper GI tract lab test are typically givenan X-ray contrast agent that aids with the radiologic imaging ofthe anatomy. One such contrast agent is sodium diatrizoate (NaDTZ),a non-volatile water-soluble ionic compound. A 0.378 m solution isprepared by dissolving 38.4 g of NaDTZ in 160. mL of water at 31.2C (the density of water at 31.2 C is 0.995 g/mL). What is the molarmass of NaDTZ? What is the vapor pressure of this solution if thevapor pressure of pure water at 31.2 C is 34.1 torr?
