When measured with a 1.00-cm cell, a 7.50 X 10-5 M solution of species A exhibited absorbances of 0.155 and 0.755 at 475 and 700 nm, respectively. A 4.25 x 10-5) M solution of species B gave absorbanees of 0.702 and 0.091 under the same circumstances. Calculate the concentrations of A and B in solutions that yielded the following absorbance data in a 2.50-em cell:
(a) 0.439 at 475 nm and 1.025 at 700 nm;
(b) 0.662 at 475 nm and 0.815 at 700 nm.
