    The % transmittance of an aqueous solution of a dye at 450 μm and 25oC is 30% for a 2 x 10-3 M solution in a 2 cm cell. Calculate optical density (OD) and molar extinction co-efficient. Find the concentration of the same dye in another solution in which % transmittance is 20% in a 1 cm cell, at same temperature and same wavelength of light.
