The molar extinction coefficients for A and B at =450 nm are ɛ=2,000. and ɛ=3000. M cm'. At A=650 nm, the molar extinction coefficients are ɛ=1,000. for both compounds. If a sample containing both species had absorbance values at 2=600 nm are A=0.070 and at 1=400 nm are A=0.185, what concentrations of A and B are present in the unknown solution? Assume that the absorbances are additive and that the measurements were made using a 1-cm cuvette. Show your work.
