Chapter 11, Problem 11A.4AE

Interpretation Introduction

Interpretation:

The molar concentration of the solute that has molar absorption coefficient $386{\text{ dm}}^3{\text{mol}}^{-1}{\text{ cm}}^{-1}$ at $540\text{nm}$ has to be calculated.

Concept introduction:

The Beer-Lambert law states that the intensity of light absorbed by a solution is directly proportional to the concentration of the solution and the path length of that the light has to travel in the solution.  The mathematical expression for Beer-Lambert law is given below.

    $A=\epsilon cL$
