Last updated: 7/26/2022

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 acetylene needed to produce 0.075 mol of carbon dioxide. Be sure your answer has a unit symbol necessary, and round it to the correct number of significant digits.
