5 Stars for showing work. Compounds A and B absorb in the UV region. A shows an absorptivity of 157 at 267 nm and a small shoulder at 312 nm with absorptivity of 12.6. B does not absorb at 267 nm, but has an absorptivity of 186 at 312 nm. A solution containing both A and B in a 1-cm cell showed an absorbance of 0.726 at 267 nm and 0.544 at 312 nm. What are the concentrations, mg/L, of A and B?
