Acetylene (C₂H₂) gas is often used in welding torches because of the very high heat produced when it reacts with oxygen (O₂) gas, producing carbon dioxide gas and water vapor. Calculate the moles of carbon dioxide produced by the reaction of 2.5 mol of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits. 10 010 X x ロ・ロ 3

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".
