WebThe higher the molar absorptivity, the lower the concentration of species that still gives a measurable absorbance value. Formula to calculate molar absorptivity. Using the Beer-Lambert Law we say that; Example: Calculate the molar absorptivity of a 2M sodium nitrate whose absorbance rate is 120 and the light path is 0.2 cm. Web8. Then, you will plot a graph of measured absorbance versus concentration to determine the molar absorptivity, ε, for the Cu(NH3)4 2+ ion. Then, you will use this value for ε to find the concentration of the Cu(NH3)4 2+ ion in an unknown sample (ie., the solution which your penny has been dissolved).
