The molar absorptivity of a solution containing and having transmittance of is to be calculated.
The molar absorptivity of a solution is defined as the capacity of a solution to absorb the particular wavelength of light incident on it. In order to calculate the molar absorptivity, first the absorbance of the solution is determined using the Beer’s law.
Now, the relation between the molar absorptivity, absorbance and concentration of the solution is given by the relation.
