Molar absorptivities (ε, M-1cm-1) of compounds X and Y were measured in pure samples at two different λ and are given below:

λ, nm X Y

250 14,350 2,505

310 2, 708 6,502

A mixture if these two compounds was tested in a 1.0 cm cell. And following

absorbances (A) were obtained:

λ, nm A

250 0.910

310 0.575

Find concentrations of X and Y in the mixture.
