Calculate Absorbance





Formula

The formula to calculate the absorbance (A) is:

\[ A = \epsilon \cdot c \cdot l \]

Where:

Definitions

Example

Let's say the molar absorption coefficient (ε) is 0.1 m²/mol, the concentration (c) is 0.5 mol/L, and the path length (l) is 1 m. Using the formula:

\[ A = 0.1 \cdot 0.5 \cdot 1 \]

We get:

\[ A = 0.05 \]

So, the absorbance is 0.05.
