Complete all of the calculations for creating a calibration curve that you will use to determine the concentration of an unknown sample in lab this week. The stock solution is 300 ppm quinine. First determine the dilution to create a25-mL solution of 1 ppm quinine solution. Then use that 1 ppm stock solution to prepare five standard solutions of quinine, 25 mL each. You can choose your concentration range but keep the max below 0.2 ppm
