How to Calculate Concentration Using Absorbance | Sciencing

Hot sciencing.com https://sciencing.com/calculate-concentration-using-absorbance-7153267.html

The amount of light absorbed is proportional to the length of the light path (l). Practically, this is the container, usually a cuvette, in which the material in question is held. The relationship between absorbance and concentration (c) is proportional. Usually, the more concentrated a substance, the more light will be absorbed.

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, C = concentration, l=path length of 1 cm)

To find the concentration for a solution that has an absorbance of 0.60, you will first need to find the slope of the BEST-FIT line. From the slope of the best-fit line together with the absorbance, you can now calculate the concen tration for that solution (i.e. Concentration = Absorbance / Slope)

How to calculate molarity from absorbance

Chemists performing spectrophotometry routinely calculate the concentration of chemical solutions from light absorbance readings. Beer's Law says that the light absorbance, A, of a solution is equal to the product of a constant, e, the width of the sample, b, and the sample concentration, c. Mathematically, this is written as A = ebc.
