Q3. A stock bottle of copper sulphate (heptahydrate) is provided in each lab (note that this substance is harmful/toxic, so you should avoid ingestion or skin contact: clean up any spillages and do not pour any copper sulphate solution down the drains). On the sheet supplied in the exam will be a mass concentration (%w/v) and volume of copper sulphate solution to be prepared. Using a volumetric flask, make up this solution and measure its absorbance at 650nm in a spectrophotometer. Record your results below: Asso of copper sulphate solution........ [Note: after use, pour your solution from the cuvette into the labelled waste pot at the workstation].

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?
