a.) The molar absorption coefficient of a substance dissolved in benzene is measured to be 802 L mol-1 cm-1 at 492 nm. Calculate what fraction of the incident light intensity of that wavelength passes through 2.97 mm of a solution of concentration 3.06 mmol/L. b.) The molar absorption coefficient of a solute at 524 nm is 103 dm3 mol-1 cm-1. When light of that wavelength passes through a 4.70 mm cell containing a solution of the solute, 59.4 per cent of the light was absorbed. What is the concentration of the solution?Ans = ______ mmol dm-3
