A 2.559 g sample containing both Fe and V was dissolved under conditions that converted the elements to Fe(III) and V(V). The solution was diluted to 500.0 mL and a 50.0 mL aliquot was passed through a Walden 4+ reductor and titrated with 17.74 mL of 0.100 M Ce . A second 50.0 mL aliquot was passed through a Jones reductor and required 44.67 mL of the same Ce4+ solution to reach an endpoint. Calculate the percentage of Fe2O3 and V2O5 in the sample
