A solution contains two unknown compounds (unknown A and B). The absorbance readings of the solution were 2.58 at 328 nm and 1.05 at 458 nm. Unknown A absorbs light at 328 nm while unknown B absorbs light at 328 nm and 458 nm. Calculate the concentrations (g/L) of unknown A and unknown B at a path length of 1 cm. (Hint: calculate the concentration of unknown B first.)
