1) Tylenol is found to absorb at
245nm(A1=668) in aqueous acid and at 257nm(A1=715) in aqueous alkali
Where A1 = Absorbancy
If an acid solution in a 1 cm cuvette was found to have an absorbance of 0.669 absorbance units, what was the concentration of tylenol in the solution? If the absorbance of a basic solution of tylenol was 2.0, what would its concentration be?
