5. A student mixed 5 mL of 3% m/v H202 with 10 mL of 0.5M IKI solution and measured
the volume of water displaced over time. Use their data to prepare a plot of volume
water displaced (mL) versus time (s) in Excel and find the rate of this run. Attach your
spreadsheet and plot to your pre-laboratory assignment.

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?
