Ores are analyzed by dissolving some of the ore and then performing an analysis of a metal (expressed in grams); usually the concentration of the metal is expressed as % of the amount of the ore (in grams) dissolved. An ore containing V was dissolved and then titrated with MnO4-. When 5.1650 g was dissolved and titrated with 0.1467 M MnO4- the titration required 22.57 mL to reach the endpoint. What was the % V in the ore?

5VO2+(aq) + MnO4-(aq) + 11H2O(l) ¡ê 5V(OH)4+(aq) + Mn2+(aq) + 2H+(aq)
