In the reaction 2 H2 + O2 -> 2 H2O, what is the mole ratio of H2O to H2?

Explanation:
In a balanced equation, the coefficients show the mole relationships between substances. Here, 2 H2 produce 2 H2O, so the ratio of water to hydrogen is 2:2, which simplifies to 1:1. That means for every mole of H2 that reacts (with enough O2), you form one mole of H2O. For example, if you had 4 moles of H2 and sufficient oxygen, you’d make 4 moles of H2O.
