The fe2 (55.845 g/mol) content of a 2.465 g steel sample dissolved in 50.00 ml was determined by tiration with a standardized 0.140 m potassium permanganate (kmno4, 158.034 g/mol) solution. the titration required 34.59 ml to reach the end point. what is the concentration of iron in the steel sample? express your answer as grams of fe per grams of steel (g fe2 / g steel).
