two species A and B react to form a colored complex AB that absorbs at 550 nm with a molar absorptivity of 465 1/(M*cm). Species A is colorless, but species B has a molar absorpivity of 110 M^-1*cm^-1 at 550 nm. The dissociation constant (Kd) for the complex is 4.00E-7. Find the absorbance at 550 nm of a solution prepared by mixing 50.0 ml of 2.00 mM A and 50.0 ml of 5.00 mM B. assume the absorbance is measured with a 1.00 cm cuvette.
