23. Photometry of a solution of iron sulfosalicylate complex gave a relative optical density of 0.29. The reference solution contained 0.0576 mg of iron in 50.0 ml, cuvette thickness 5 cm. Determine the concentration of iron in the solution if it is known that the molar extinction coefficient of the complex under these conditions was 3000.
