You are tasked with creating a calibration curve for the absorbance of cobalt solutions of various concentrations. You must prepare 5 standards with concentrations between 1.00 mg/L and 10.0 mg/L Co2+. You have a stock solution with a concentration of 40 mg/L Co2+ and all the standard lab glassware including transfer pipets and flasks. Explain how you would make your 5 standard solutions of various concentrations, including what glassware you would use to measure and prepare each solution.
