How many grams of carbon dioxide would be formed if 38.9 g c2h2 reacted completely with oxygen

2C₂H₂ + 5O₂ = 4CO₂ + 2H₂O

m(CO₂)/{4M(CO₂)} = m(C₂H₂)/{2M(C₂H₂)}

m(CO₂)=2M(CO₂)m(C₂H₂)/M(C₂H₂)

m(CO₂)=2*44g/mol*38.9g/26g/mol = 131.7 g

131.7 grams of carbon dioxide would be formed

What do you mean by that? like the contents? the thc level?

Maybe you should get some from your teacher and learn more so you can get your grades up and maybe study a bit more
