Question
Chapter 9, Problem 9D.3BST
Interpretation Introduction
Interpretation:
The molar absorption coefficient
Concept Introduction:
Beer’s lamberts law:
The Beer-Lambert law states that the quantity of light absorbed by a substance dissolved in a fully transmitting solvent is directly proportional to the concentration of the substance and the path length of the light through the solution.
Where A is the absorbance of the solution,
L is the path length of the solution.
c is the concentration of the solution.
