For an analytical chemistry lab, a student was asked to use the standard addition method to determine the concentration of iron in an iron ore. The student decided to use the standard addition method to account for matrix effects and to use Atomic Absorption Spectroscopy. The resulting data obtained by the student is shown in the table below:

Using the standard addition method, determine the amount of Fe (in ppm) in the iron ore. For full marks, please include the graph of your data (you can print off your Excel graph) and show how you calculated the concentration of Fe in the iron ore.
