In the reaction #2CO(g) + O_2(g) -> 2CO_2(g)#, what is the ratio of moles of oxygen used to moles of #CO_2# produced?

Why the ratio of dioxygen to carbon dioxide is
Explanation:
You have given the stoichiometric equation, which states UNEQUIVOCALLY that 2 mole of carbon monoxide reacts with 1 mole of dioxygen gas to give 2 mole of carbon dioxide. We could also state that 1 volume of carbon monoxide, and 2 volumes of dioxygen, react to give 2 volumes of carbon dioxide.
Look at the stoichiometry of the reaction. One mole of dioxygen reacts with 2 moles of carbon monoxide to give 2 moles of carbon dioxide. Because products and reactants are conceived to hold identical temperatures, and pressure is constant, one VOLUME of dioxygen reacts with 2 VOLUMES of carbon monoxide to give 2 VOLUMES of carbon dioxide.
Explanation:
First check to see if the equation is balanced. It is so now let's find the ratio.
The ratio is the stoichiomeric coefficient of the element or compound.
Oxygen: Carbon dioxide
