    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?
