WebReaction stoichiometry describes the 2:1:2 ratio of hydrogen, oxygen, and water molecules in the above equation. The molar ratio allows for conversion between moles of one substance and moles of another. For example, in the reaction 2 CH3OH + 3 O2 → 2 CO2 + 4 H2O the amount of water that will be produced by the combustion of 0.27 moles of CH WebRates: Average Rates, Determination of Rates from Stoichiometry and Changes of Other Chemicals; Simple Rate Calculations 9.
