Radiation of wavelength 280 nm passed through 1.0 mm of a solution that contained an aqueous solution of the amino acid tryptophan at a concentration of 0.50 mmol L^(-1). The light intensity is reduced to 54% of its initial value. Calculate the absorbance and the molar absorption coefficient of tryptophan at 280 nm. What would be the transmittance through a cell of thickness 2.0 mm?

The transmittance of an aqueous solution containing the amino acid tyrosine at a molar concentration of 0.10 mM was measured at 240 nm in a cell of length 5.0 mm. Calculate the absorbance of the solution and the molar absorption coefficient of tyrosine at that wavelength. What would be the transmittance through a cell of length 1.0 mm?
