Some indoor air-purification systems work by converting a little of the oxygen in the air to ozone, which oxidizes mold and mildew spores and other biological air pollutants. The chemical equation for the ozone generation reaction is: It is claimed that one such system generates 4.00 g O3 per hour from dry air passing through the purifier at a flow of 5.00 L/min. If one liter of indoor air contains 0.280 g of O2, what mole fraction of O2 is converted to O3 by the air purifier?   What is the percent yield of the ozone generation reaction?

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".
