Zinc(II) and the ligand L form a 1: 1 complex that absorbs strongly at 600 nm. As long as the molar concentration of L exceeds that of zinc(II) by a factor of 5, the absorbance depends only on the cation concentration. Neither zinc(II) nor L absorbs at 600 nm. A solution that is 1.59 X 10-4 M in zinc(II) and 1.00 X 103 M in L has an absorbance of 0.352 in a 1.00-cm cell at 600 nm. Calculate
(a) The percent transmittance of this solution.
(b) The percent transmittance of this solution in a 2.50-cm cell.
(c) The molar absorptivity of the complex.
