A 2.65 g sample containing both Fe and V was dissolved under certain conditions

Question

A 2.65 g sample containing both Fe and V was dissolved under certain conditions and diluted to 500.00 mL. A first 50.00 mL aliquot was taken and passed through a Walden reductor to form Fe^2+ and VO^2+ ions. The titration of this solution required 1484 mL of 0.1000 M Ce^4+ to reach end point. A second 50.00 mL aliquot was passed through a Jones reductor to form Fe^2+ and V^2+ ions. The titration of the second solution required 40.26 mL of 0.1000 M Ce^4+ solution to reach an end point. Calculate the percentage of Fe and V in the sample.
