Compounds A and B absorb in the ultraviolet region. Compound A exhibits an absorption maximum at 267nm (a=157) and a shoulder at 312nm (a=12.6). Compound B has an absorption maximum at 312nm (a=186) and does not absorb at 267nm. A solution containing the two compounds exhibits absorbances (using a 1.00cm cell) of 0.726 and 0.544 at 267 and 312nm, respectively. What are the concentrations of A and B in mg/mL? Note: The aborptivity values are given in units of L/g.cm.
