Exercise 1

Assume you are to determine the blood serum level of cholesterol by the single standard method. The absorbance data obtained are: A standard = 0.350 (250 mg/100 mL); A sample , = 0.390; and A correction = 0.02. Calculate the concentration of cholesterol in mg/100 mL. What would be the % error if: A correction were not used?
