As the pharmacist at a rural clinic in Ecuador, you have been asked to make 550.0 mL of an eye wash solution (0.250 M H_3 BO_3) using deionized water and a stock boric acid solution (3.75 M H_3 BO_3). Your technician offers to make the solution. She adds enough water to 50.0 mL of the stock solution to make a 250.0 ml of dilute boric acid. a. What is the molarity of the solution made by your technician? Show your work. Box your final answer. b Did your technician make the solution you need? If not, explain (using words) how you could correct the concentration (not by starting over.... ) using some of the solution she prepared. Show all calculations.
