Question
**Problem Statement: Vanadium in Ore Sample**

The problem involves determining the mass percent of vanadium (V) in a 0.5000-g sample of ore. The vanadium (V) ion is converted to VO₂⁺ ions. The amount of VO₂⁺ in the solution is determined through a reaction with an acid solution of KMnO₄. The balanced chemical equation for the reaction is:

\[ 5\text{VO}_2^+ (aq) + \text{MnO}_4^- (aq) + 11\text{H}_2\text{O} \rightarrow \text{Mn}^{2+} (aq) + 5\text{V(OH)}_4^+ (aq) + 2\text{H}^+ (aq) \]

**Question:**

What is the mass percent of vanadium in the ore if 26.45 mL of 0.02250 M permanganate solution is required for complete reaction?
