28. In the photometric study of the thisulphosalicylate complex of iron (III), the following results were obtained:
Sk*102 mg/cm3 0.050 0.100 0.150 0.200 0.250 0.300
А416 (l=2cm) 0.104 0.208 0.313 0.415 0.521 0.624
Construct a calibration graph, calculate the value of the molar absorption coefficient of the complex, as well as the concentration of iron (III) in the test solution, if its optical density, measured in the same cuvette, is 0.374.
