Question #7f7a2

Using Beer-Lambert Law

Explanation:

The relationship between absorbance $A$ $A$ and concentration $C$ $C$ is giving by the Beer-Lambert law:

$A = ε \times l \times C$ $A=epsilon xx l xxC$

where, $ε$ $epsilon$ is the molar absorptivity of the solution, $l$ $l$ is the light path.

Therefore, if you have the absorbance $A$ $A$ , the concentration can be calculated by: $C = \frac{A}{ε \times l}$ $C=A/(epsilonxxl)$

Here is a video featuring a full experiment on Beer-Lamber Law:
