## How To Find Molarity From Absorbance

When you take an absorbanc spectrum, the molar absorptivity constant is changing up and down and all around, but when you are working with a calibration plot, and are only changing the concentration, it shows a linear relationship between absorbance and concentration.

- Both are plotting absorbance, but the spectrum plots it vs. wavelength (molar absorptivity constant) and the calibration plot is vs. concentration. Try a Math Question about the two graphs above! Show/hide comprehension question...
- I am interested to know which formula can be used to determine the absorption coefficient (alpha) from an absorbance. Absorbance is obtained from UV-Vis measurement.
- Define the variables to calculate the molar absorptivity. The absorbance (A) is the amount of light within a given wavelength that is absorbed by the solution.
- A mole is a measure of the number of molecules in a given volume. In scientific notation, one mole equals approximately 6.022x10^23, where the caret ^ indicates exponentiation.
