Calculate Concentration from Absorbance





What is Concentration?

Concentration is the amount of a substance in a given volume of solution. It can be calculated using Beer's Law, which relates absorbance to concentration.

Formula

The formula to calculate concentration from absorbance is:

\[ c = \frac{A}{\epsilon \cdot l} \]

Example Calculation

Consider the following details:

Using the formula:

\[ c = \frac{0.5}{100 \cdot 1} = 0.005 \, \text{mol/L} \]
