A solution contains 1.0mg of KMnO4/L. When measured in a 1.00cmcell at 525 nm, the transmittance was 0.300. When measured undersimilar conditions at 500 nm, the transmittance was 0.350. (a)Calculate the absorbance A at each wavelength, (b) Calculate themolar absorptivity at each wavelength. (c) What would T be if thecell length were in each case 2.00cm? (d) Calculate theabsorptivity (if concentration is in mg/L) for the solution at eachwave length.
