Light of wavelength 256 nm passes through a 1 mm path length cell that contains a 0.05 M solution of benzene. The light is reduced to 16 percent of its initial value. Calculate the optical density and extinction coefficient of the sample. What would be the transmittance through a cell of path length 2 mm?© BrainMass Inc. brainmass.com March 4, 2021, 5:41 pm ad1c9bdddf
Approach: Use the Beer Lambert Law to calculate optical density and extinction coefficient.
Beer Lambert Law:
A=elC where A=absorbance, e=extinction coefficient, C=concentration ...
