123. Solving a chemistry problem

4. At λ=620 nm, the optical density of the solution containing 8.55*10-5 mol/l of component A was 0.362, and the optical density of the solution with component B at a concentration of 2.37*10-4 mol/l was 0.055 at this the same wavelength. Calculate the optical density of a solution containing 1.61*10-4 mol/l of component A and 7.35*10-4 mol/l of component B at λ=620 nm. In all cases, measurements in the cuvette I=1.0 cm.
