When light of wavelength 410 nm passes through 2.5 mm of a solution of the dye responsible for the yellow of daffodils at a concentration 0.433 mmol dm^(−3), the transmission is 71.5 percent.
Calculate the molar absorption coefficient of the coloring matter at this wavelength and express the answer in centimeters squared per mole (cm^2 mol^(-1)).
