29. Solving a chemistry problem

3. The optical density of iron sulfosalicylate, measured at λ=433 nm in a cuvette with a layer thickness of 2 cm, is 0.15. For the reaction, 4.0 ml of 5.82 * 10-4 mol / l iron solution was taken and brought to 50 ml. Calculate the value of the molar absorption coefficient of the resulting solution at λ=433 nm.
