## What is the relationship between absorbance and concentration?

There is a relationship between concentration and absorbance. This relationship is expressed by the Lambert-Beer law, which is more commonly known as Beer’s law. This law states that the absorbance of a light absorbing material is proportional to its concentration in solution.

## What is the unit of absorbance?

Absorbance is a measure of the quantity of light absorbed by a sample. It is also known as optical density, extinction, or decadic absorbance. Typical units of absorbance are called “absorbance units,” which have the abbreviation AU and are dimensionless.
