How can you calculate the concentration of a solution with UV-vis spectroscopy if you do NOT know the molar absorption coefficient? (a) Add blue dye to the sample and then subtract the blank sample's absorbance. (b) Use Beer's Law by assigning the molar absorption coefficient a value of 1 (e = 1). (c) Create a calibration curve which is a plot of absorbance vs concentration. (d) Calculate the rate constant. (e) Divide the measured absorbance by the product of l´e.

A 0.1 g amine-containing compound is dissolved in water then diluted to 100 mL. You subject it to spectroscopic analysis, in order to get the concentration of amine in this compound. Next, you get 1 mL of the previously diluted sample then dilute it again to 250 mL for measurement. Then, you fill 3/4 of a 1-cm cuvette with this diluted sample, and you run an analysis using an AAS. The recorded absorbance is 0.545 at 410 nm. What is the molecular weight of the compound?
