How do you calculate concentration from absorbance?

Mar 18, 2014You will use Beer's law. A = εmCl The basic idea here is to use a graph plotting Absorbance vs. Concentration of known solutions. Once you have that you can compare the absorbance value of an unknown sample to figure out its concentration. You will be applying Beer's law to calculate the concentration. The equation for Beer's law is: A = εmCl (A=absorbance, εm = molar extinction coefficient
