If 2 moles of water decomposes, the products that will form are 2 moles of hydrogen gas and one mole of oxygen gas. If a reaction is conducted that consumes 20.0 mL of water, what volume of oxygen gas will be produced (in L)? The density of water is 0.998 g/mL. Assume that 1 mole of oxygen gas has a volume of 22.414 L. Use these atomic masses: H = 1.008 amu; O = 15.999 amu Not these answers: 12.32 12.417 18.015 0.55

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
