Calculate Extinction Coefficient



Formula

The formula to calculate the molar extinction coefficient is:

\[ E = \frac{A}{mc} \]

Where:

What is Extinction Coefficient?

The extinction coefficient is defined as the ratio of absorbance to the molar concentration of a solution.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ E = \frac{0.5}{0.1} = 5 \]

The Extinction Coefficient is 5.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ E = \frac{1.2}{0.3} = 4 \]

The Extinction Coefficient is 4.
