7. To an aliquot of 25.00 cm3 of a solution containing 4.50 μg / cm3 of iron (III), an excess of potassium rhodanide was added and diluted to a final volume of 50.00 cm3. What is the optical density of the obtained solution, measured at 570 nm in a cuvette with = 2 cm. The molar absorption coefficient of the rhodanide complex is 5500.
