Answer:
9.0 mol
Explanation:
- C₂H₄(g) + 3O₂(g) → 2CO₂ (g) + 2H₂O (g)
In order to <u>convert from moles of CO₂ to moles of O₂</u>, we need to use the <em>stoichiometric coefficients</em> in the balanced reaction. We use a conversion factor that has moles of CO₂ in the denominator and moles of O₂ in the numerator:
- 6.0 mol CO₂ *
= 9.0 mol O₂
