Answer:

1.8 moles of CO₂

Explanation:

The equation for the combustion of propane is given by;

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

We are given;

  • Moles of C₃H₈ = 3 moles
  • Moles of O₂ = 3 moles

We are required to determine the theoretical number of moles of CO₂ produced.

  • From the equation, 1 mole of C₃H₈ reacts with 5 moles of O₂
  • We are given, 3 moles of O₂ and 3 moles of C₃H₈, thus, oxygen is the limiting reactant since it has a higher ratio.
  • Therefore, using mole ratio we can determine the number of moles of CO₂ produced.

Mole ratio of O₂ to CO₂ is 5 : 3

Thus, moles of CO₂ = moles of O₂ × 3/5

                                 = 3 moles × 3/5

                                = 1.8 moles

Hence, the theoretical number of moles of CO₂ from the reaction is 1.8 moles
