9. The molar absorption coefficient of the complex of iron (III) with sulfosalicylic acid composition 1:1 at λ = 416 im equals 4000 mol-1*l*cm-1. Calculate the weight of the Fe2(SO4)3*9H2O sample, which must be dissolved in 50 ml of water in order to obtain a colored solution from 5 ml of the prepared solution after appropriate processing and dilution to 25 ml with a transmission value of 17.8% with a cuvette thickness of 20 mm.9.
