6. A stock solution of iron was prepared by dissolving 1.452g FeCl3 in water, reacting with thiocyanate to form brick red ferric thiocyanate, then topping up with water to 1L in a volumetric flask. The solution was then diluted by taking a 10mL aliquot and toping it up with water in a 250mL volumetric flask. This sample had a %T reading of 70.0% at 450nm. a) what is the absorbance of the solution? b) what would be the concentration of Fe in a sample having absorbance of 0 3492
