STEP 0: Pre-Calculation Summary

Formula Used

Slope of Line = Molar Extinction Coefficient*Thickness of Cell
m = ε*l
This formula uses 3 Variables

Variables Used

Slope of Line - The Slope of Line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.
Molar Extinction Coefficient - (Measured in Square Meter per Mole) - The Molar Extinction Coefficient is a measure of how strongly a chemical species or substance absorbs light at a particular wavelength.
Thickness of Cell - (Measured in Meter) - Thickness of Cell is useful in calculating the concentration of a solution on the basis of its light absorption.

STEP 1: Convert Input(s) to Base Unit

Molar Extinction Coefficient: 19 Square Centimeter per Mole --> 0.0019 Square Meter per Mole (Check conversion here)
Thickness of Cell: 50.5 Nanometer --> 5.05E-08 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

m = ε*l --> 0.0019*5.05E-08

Evaluating ... ...

m = 9.595E-11

Concentration of Solution

LaTeX Go Concentration of Solution = Absorbance/(Thickness of Cell*Molar Extinction Coefficient)

Beer-Lambert law given Intensity of Radiation

LaTeX Go Absorbance = log10(Intensity of Incident Radiation/Intensity of Transmitted Radiation)

Absorbance using Beer-Lambert Law

LaTeX Go Absorbance = Molar Extinction Coefficient*Concentration of Solution*Thickness of Cell

Intensity of Incident Radiation

LaTeX Go Intensity of Incident Radiation = Intensity of Transmitted Radiation*10^(Absorbance)

What is Beer- Lambert Law?

Beer-Lambert law is useful in calculating the concentration of a solution on the basis of its light absorption. This law relates the intensity of the transmitted monochromatic light to the concentration of the solution and the thickness of the cell in which the solution is kept.
The molar extinction coefficient of a substance can be determined using a colorimeter or a spectrophotometer as follows. The absorbances of a solution are measured at different
known concentrations using a cell of known thickness (l). The plot of absorbance, A against Concentration of solution, c gives a straight line and its slope is equal to εl.
