Well, it depends on what your reactants are

Explanation:

It's possible that the 2 moles may have "disappeared" if the product includes a gas and the reaction took place in an open system. If a gas isn't one of your products, perhaps there's a missing product or something like that. You'd need to know what the reactants are to give a more specific answer.
