Using colorimetry, you are finding the absorption spectra of a colored compound. after diluting your sample by 15-fold, you find its max to be 450 nm, yielding an absorption of 0.65. a. given that the initial concentration of your colored compound is 8 mg/ml, and its molecular weight is 16,300 g/mol, calculate the diluted concentration of your colored compound (in m). b. calculate the extinction coefficient for your colored compound.
