Concentration from Absorbance Formula
The following formula is used to calculate a concentration from absorbance.
C = A / (L * e)
- Where A is the absorbance
- L is the path length
- e is the extinction coefficient
To calculate the concentration from absorbance, divide the absorbance by the product of the path length and extinction coefficient.
A concentration is defined as the total amount of a substance in a given space.

How to calculate concentration from absorbance?
- First, determine the absorbance.
Calculate the absorbance.
- Next, determine the path length.
Measure the total path length of absorbance.
- Next, determine the extinction coefficient.
Calculate the extinction coefficient.
- Finally, calculate the concentration.
Calculate the concentration using the equation above.
A concentration is a measure of the total amount of substance contained is a certain area or volume.
