SOLVED: A. The absorbance of a cationic iron(II) sample solution was measured in a spectrophotometer, but the instrument returned an error because the absorbance was too high. The sample was then diluted by using a pipette to take 100.0 μL of the sample and injecting it into a cuvette already containing 2.00 mL of water (total volume is 2.00 mL 100.0 μL). The absorbance value of the diluted solution corresponded to a concentration of 7.66×10^(-6) M. What was the concentration of the origina
