For the reaction
C2H4(g) + 302(g) → 2002 (g) + 2H20 (8)
if 6.0 mol of CO2 are produced, how many moles of Oz were reacted?
4.0 mol
0 7.5 mol
9.0 mol
o none of these
O 15 mol

Answer:

9.0 mol

Explanation:

  • C₂H₄(g) + 3O₂(g) → 2CO₂ (g) + 2H₂O (g)

In order to convert from moles of CO₂ to moles of O₂, we need to use the stoichiometric coefficients 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 * [tex]\frac{3molO_2}{2molCO_2}[/tex] = 9.0 mol O₂
