The amount of Fe in a 0.4891-g sample of an ore is determined by titrating with K2Cr207. After dissolving the sample in HCI, the iron is brought into a +2 oxidation state using a Jones reductor. Titration to the diphenylamine sulfonic acid end point requires 36.92 mL of 0.02153 M K2Cr207. Report the ore's iron content as %w/w Fe203. In this problem, which is the titrant? O K2Cr207 O diphenylamine sulfonic acid Fe203 HCI Fe2+

To analyze the amount of iron (Fe; Mw = 55.85 g/mol) contained in an ore sample, the sample was digested with acid and diluted to 50 mL with water. This solution was then treated with 25.00 mL of 0.2922 M EDTA. The excess EDTA was back titrated with 6.47 mL of 0.0843 M Zn2+ to reach the equivalence point. How many grams of Fe contained in the ore sample?
