Iron (II) ions catalyze the oxidation of luminol. The intensity of the resulting chemiluminescence has been shown to increase linearly with iron (ii) concentration from 10^-10 to 10^-8 M. Exactly 1.00ml of water was added to a 2.00ml aliquot of an unknown Fe(II) solution, followed by 2.00ml of a dilute H2O2 solution and 1.00ml of an alkaline solution of luminol. The chemiluminescent signal from the mixture was integrated over a 10.0 s period and found to be 16.1. To a second 2.00ml aliquot of the sample was added 1.00ml of a 5.15 x 10^-5 M Fe(II) solution followed by the same volume of H2O2 and luminol. The integrated intensity was 29.6. Calculate the Fe(II0 molarity of the sample.
