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?
1. A 50.00 mL stock CaCl2 solution was diluted with water in a 250.0-mL volumetric flask. A 25.00 mL aliquot of this was further diluted to a final volume of 100.0 mL. Finally, 20.00-mL aliquot of the resulting solution was analyzed and found to contain 0.1500 M CaCh2 Solve for the concentration of the stock solution in M. 2. A 50.00 mL stock CaCl2 solution was diluted with water in a 250.0-mL volumetric flask. A 25.00 mL aliquot of this was further diluted to a final volume of 100.0 mL. Finally, 20.00-mL aliquot of the resulting solution was analyzed and found to contain 0.1200 g CaCl2 Solve for %w/v CaCl2 in the stock solution.
A 1 mL microbial suspension comparable to 1 mL of 1.0 McFarland standard was subjected to a series of dilutions. An aliquot of 0.2 mL was transferred into a 100-mL volumetric flask and diluted with sterile saline solution to its final volume. Then a 0.1 mL of the resulting solution was transferred into a 50-mL volumetric flask diluted to its final volume. What would be the final concentration?

A student was given a stock aluminum(III) solution with a concentration of 5.000 parts per million (ppm). (ppm are defined as mg/L for dilute aqueous solutions.) The student prepared five 100 mL standard solutions and an unknown as described in the procedure section of the experiment. The absorbance of each solution was read at 565 nm, using the blank to set zero absorbance. The results are tabulated below. Solution Volume of Al(III) stock solution used (mL) Absorbance 1 8.00 0.701 2 6.00 0.548 3 4.00 0.378 4 2.00 0.208 5 1.00 0.123 Unknown --- 0.534 3. What is your best estimate of the Al(III) concentration of the unknown sample in the cuvet based upon where its absorbance falls on the standard curve?
