A 4.48 mg sample of a compound has a molar mass of 158.03 g/mol was dissolved in a 1000 mL volumetric flask. A 1.00 mL aliquot was withdrawn, placed in a 10.00 mL volumetric flask, and diluted to the mark. A 10.00 mL aliquot was placed in a 1.00 cm cell and percent transmittance of 30.9% at 520 nm. Calculate the molar absorptivity of KMnO4, at 520 nm.
