In its protonated form, bromothymol blue has a molar absorptivity of 13800 m-1•cm-1 at 435 nm. at the same wavelength, the deprotonated form of bromothymol blue has a molar absorptivity of 3410 m-1•cm-1. if a solution contains 2.80 × 10-5 m protonated bromothymol blue and 5.00 × 10-5 m deprotonated bromothymol blue, what is the absorbance of the solution in a 1.00-cm sample cell at 435 nm?
