A 5.00-mL aliquot of a solution that contains 2.01 ppm Fe2+ is treated with an appropriate excess of thiocyanate and diluted to 50.0 mL. The molar absorptivity of a Fe2+-thiocyanate solution at 580 nm is 7000 L mol-1 cm-1. What is the absorbance of the above diluted Fe2+-thiocyanate solution at 580 nm in a 10.00-cm cell?
