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.
