Question

You are measuring the concentration of Fe2 in a sample by measuring the absorbance of its complex with ferroxine. Your sample, measured in a 1.00-cm pathlength cuvette, has an absorbance of 0.347 while the reagent blank in the same cuvette has an absorbance of 0.040. What would be the absorbance reading of these two solutions if measured in a cuvette with 4.00 cm pathlength?
