At l=530 nm:aCuSO4=7.544L/mol-cm aKMnO4= 3.645 L/mol-cm
At l=800nm: aCuSO4=2.908L/mol-cm aKMnO4= 5.412L/mol-cm you use a celleith a path length of 1.0cm

An unknown solution containing both CuSO4 and KMnO4 gave an absorbance reading of 0.679 at 530nm and an absorbance of 0.525 at 800nm. What is the molar concentrations of KMnO4 and CuSO4 in your unknown?
