1. (6 pts.) It is desired to determine the amount of iron in a sample of whole cow's milk by
AA per flame. 5.00 mL of the milk is taken, acid digestion is applied, the resulting solution is transferred to a 25 mL flask and diluted to the mark. A 5.0 L aliquot of the resulting solution is diluted to a volume of 1.0 mL. This solution gave an absorbance of 0.235. The calibration curve resulted in the regression equation y = 5.068 x (mg/L) + 0.012. Calculate the number of g of Fe present in one cup (240 mL) of whole cow's milk.
