# (a) Interpretation: Theabsorbance of the solution for the percent transmittance for half of 5.38 % is to be calculated. Concept introduction: The absorbance of the solution is the ability of the solution to absorb the monochromatic light passing through it. The absorbance of the solution is defined as the ratio of the intensity of light incident on the solution to the intensity of light absorbed by the solution. The relation between the absorbance and transmittance of a solution is given by Beer’s law. A = − log T
