How do I calculate concentration from absorbance?
Posted December 2, 2020

Answer
Use the Beer-Lambert Law to calculate the concentration of a solution from the absorbance measurements. 
Rearrange the formula by solving for c: 
Where:
= the molar absorptivity
ε = the molar extinction coefficient
= fixed path length
= the concentration
