The Fe2+Fe2+ (55.84555.845 g/mol) content of a 2.2472.247 g steel sample dissolved in 50.0050.00 mL of an acidic solution was determined by tiration with a standardized 0.1200.120 M potassium permanganate (KMnO4KMnO4, 158.034158.034 g/mol) solution. The titration required 29.2929.29 mL to reach the end point. What is the concentration of iron in the steel sample? Express your answer as grams of FeFe per gram of steel. MnO−4+8H++5Fe2+↽−−⇀Mn2++5Fe3++4H2OMnO4−+8H++5Fe2+↽−−⇀Mn2++5Fe3++4H2O concentration: g Fe/g steel (please type answer not write by hend)
