Describe exactly how to prepare a series of 8 solutions of a reagent with dilution factor of 2 within the series and the most concentrated solution with concentration of c1 = 50.0 mM. The stock solution has the concentration of 1.00M. Find the concentrations of all 8 solutions in the series, and the volumes of water and a more concentrated solution (use any numbers) to prepare each of the solutions in the series.

Describe in detail how you would make a series of four standards ranging from 1 to 100 ppm given the following constraints. a. Your stock solution is 1000 ppm. b. The available pipets have volumes of 2.00 mL, 3.00 mL, and 5.00 mL. c. The available volumetric flasks have volumes of 10.00 mL, 25.00 mL, 50.00 mL, and 100.00 mL. d. You need to make at least 10.00 mL of each of your four standards.

Intraveneous medications are aqueous solutions that are administered directly into a vein. Some medications are manufactured at a higher concentration than prescribed. For these medications, a portion of the more concentrated stock solution is mixed with a sterile solution that does not contain the drug before being administered to a patient. If a doctor orders an injection of a 1.99% (m/v) solution of a medication, how many milliliters of the diluted solution can be prepared from 54.0 mL of a...
