Zinc (II) and the ligand L form 1:1 complex that absorbs strongly at 600.

Zinc (II) and the ligand L form 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 five the absorbance depends only on the cation concentration. Neither zinc(II) nor L absorbs at 600.nm. a solution that is 1.59 * 10^-4 M in zinc(II) and 1*10^-3 M in L has an absorbance of .352 in a 1 cm. cell at 600 nm. (a) calculate the percent transmittance of this solution,(b) the percent transmittance in 2.50 cm cell (c) the molar absorptivity of the complex.Pleas give complete details
