Calculate the concentration of the reaction solution: At the end of synthesizing the dye Malachite Green, a 25mL reaction solution is recovered. You made five consecutive dilutions with a ratio of 1:10(1ml of the previous solution: to 10ml new solution) and performed a UV-Vis analysis of the last dilution (dilution 5). At the Lamda max(616.5nm ), the Absorbance is 0.855. The cuvette is 1cm on each side. Considering that the molar absorptivity in an aqueous solution is 148900M1cm1 (measured at 616.5nm ), calculate the molar concentration of the original reaction solution
