A = ebc
You have A.
You want e.
You have b.
Convert 80 ppm to mols/L and substitute; solove for e.
(Note: Remember that 1 ppm = 1 mg/L; therefore, 80 ppm is 80 mg/L. That should make it easy to convert to mols/L KMnO4)
an 80ppm of KMno4 produced an absorbance of 0.4 in a 1.0cm cuvette. Calculate the molar absorptivity of KMno4
