Moles to Moles Calculations When we write a balanced equation...for example: We are saying that for every 2 moles of H2O2 that decompose, we get 2 moles of H2O and 1 mole of O2. But suppose we didn't start out with 2 moles of H2O2. Suppose we started out with 1 mole of H2O2. I hope you see that we would get 1 mole of H2O and 1/2 mole of O2. Halving the starting material gives half the products.
