How To Calculate Concentration From Absorbance And Wavelength

How To Calculate Concentration From Absorbance And Wavelength. Absorbance will vary with wavelength, but you can't get one from the other, they are independent of each other. The height of the absorption peaks is directly proportional to the concentration of the species.
