(a) the absorbance of a 4.47 × 10^-5 M solution of the complex at 580 nm in a 1.00-cm cell.
(b) the absorbance of a solution in a 2.50-cm cell in which the concentration of the complex is one half that in(a).
(c) the percent transmittance of the solutions described in (a) and (b).
(d) the absorbance of a solution that has half the transmittance of that described in (a).
