How do you find the number of moles for this reactant.

I have this chemical equation : 5(H2C2O4) + 2(KMnO4) + 3(H2SO4) = ECT.

I need to know how to find the number of moles for 2(KmnO4) when i have.5150g of 5(H2C2O4), or .08878 mol of 5(H2C2O4).

(for all you who are against giving answers, this is not the whole problem, I can just finish the problem once I understand this part)
