A sample of steel was dissolved and the manganese present was converted to MnO4– (aq). Water was then added to give a final solution volume of 100.00 mL. A sample of this solution was examined and was found to have an absorbance at 525 nm of 0.600 (pathlength = exactly 1 cm). What is the concentration of MnO4– in the solution? (The molar absorptivity is 3.62 × 103 L/(mol cm).)
