The concentration of Fe3+ and Cu2+ in a mixture can be determined following their reaction with hexacyang ruthenate (II), which forms a blue-purple complex with Fe3+ (max=550 nm), and a pale green complex with Cu2+ (max =396 nm). The molar absorptivities in M/cm for the metal complexes at the two wavelengths are summarized in the following table. When a sample containing Fe3+ and Cu2+ is analysed in a cell with a path length of 1.00 cm, the absorbance at 550 nm is 0.183, and the absorbance at 396 nm is 0.109. What are the molar concentration of Fe3+ and Cu2+ in the sample? (3 Marks) Metal ions 550 E398 Fe3+ 9970 84 Cu+ 34 856
