When measured with a 1.00-cm cell, a 7.50 3 10-5
M solution of species A exhibited absorbances of 0.155 and 0.755 at 475 and 700
nm, respectively. A 4.25   10-5 M solution
of species B gave absorbances 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-cm 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.
