1. You wish to determine the %concentration of a stock solution of brilliant blue FCF (MW=792.8grams/mole; extinction coefficient2s=97000M'cm''). You make a 1:50 dilution of stock and then you take lul from your 1:50 dilution and dilute up to 1ml in a 1cm diameter cuvette. You obtain an A625=0.1. What is your total dilution factor? What is the % concentration of the dye in the original stock? 625
