Page 2: IN Page 3: 3 Page 4: 4 Page 5: 5 Place the following steps in the order that would allow you to determine the concentration of an unknown sample using spectrophotometry. 800 Next Page Create a calibration curve that is a plot of concentration of your known standards vs absorbance. Prepare a blank sample. Record the absorbance of your sample with an unknown concentration. Using your calibration curve and the absorbance of your unknown, extrapolate to determine the concentration of your unknown. Prepare as series of standard samples of known concentration with a range from dilute to concentrated. Analyze the standard samples with known concentrations, including the blank, to obtain an absorbance value for each sample. Page 1 of 5
