![Luke needs to measure the iron (Fe) content of a 2.007 g steel sample. He starts by completely converting the iron in the steel to
Fe²+ and dissolving it in 50.00 mL of water. Then, Luke determines the amount of Fe²+ by reacting it with a standardized
aqueous 0.150 M potassium permanganate (KMnO4) solution.
Mn²+ + 5 Fe³+ + 4H₂O
The titration of the Fe²+ solution requires 37.47 mL KMnO, solution to reach the end point.
What is the percentage by weight of iron (Fe) in the steel sample?
