Oxyacetylene torches used in high-temperature welding use a combination of oxygen and acetylene. The combustion of acetylene (C2H2) occurs in these torches. What volume of acetylene is reacted if 325 mL of oxygen are consumed in the reaction?

a. 130 mL
b. 65 mL
c. 650 mL
d. 813 mL
e. 325 mL

first, you need a balanced reaction

2C2H2 + 5O2 >>> 4CO2 + 2H2O

the correct molar ration is 2/5. So multiply 325 by 2/5 for your answer
