Interpretation Introduction

Interpretation:

The molar absorptivity of a solution containing A and having transmittance of 64.1% is to be calculated.

Concept introduction:

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.

A=logT

Now, the relation between the molar absorptivity, absorbance and concentration of the solution is given by the relation.

A=εbc
