Question: At 400 nm, compound A has a molar extinction coefficient of 4400 cm-1M-1, and compound B has a molar extinction coefficient of 92.5 cm-1M-1. At

At 400 nm, compound A has a molar extinction coefficient of 4400 cm-1M-1, and compound B has a molar extinction coefficient of 92.5 cm-1M-1. At 600 nm, compound A has a molar extinction coefficient of 333 cm-1M-1, and compound B has a molar extinction coefficient of 990 cm-1M-1. A mixture of compounds A and B is analyzed by spectrophotometry. The absorbance of the mixture at 400 nm is 0.350. The absorbance of the mixture at 600 nm is 0.866. The path length of the sample (b) is 1 cm. What are the concentrations of A and B in this mixture?
