Ferric oxalate decomposition is really about tracking electron transfer in a redox reaction. The key is to recognize that oxalate ions ($\text{C}_2\text{O}_4^{2-}$) are the species being oxidized to $\text{CO}_2$, while permanganate ($\text{MnO}_4^-$) is reduced to $\text{Mn}^{2+}$. Balance the half-reactions to find how many moles of permanganate are needed per mole of oxalate, then scale up for five moles of ferric oxalate.
