Final answer:

To determine how many moles of carbon dioxide are produced, we can use the balanced chemical equation and the given amounts of C₃H₈ and O₂. From the equation, we can see that for every 1 mole of C₃H₈, 3 moles of CO₂ are produced. By converting the given mass of C₃H₈ to moles and using the mole ratio, we can find the number of moles of CO₂ produced.

Step-by-step explanation:

To determine how many moles of carbon dioxide are produced, we need to use the balanced chemical equation and the given amounts of C₃H₈ and O₂. The balanced equation for the combustion of C₃H₈ is:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

From the equation, we can see that for every 1 mole of C₃H₈, 3 moles of CO₂ are produced. Therefore, to find the number of moles of CO₂, we can use the given mass of C₃H₈ to convert to moles and then use the mole ratio to find the number of moles of CO₂.

First, convert the mass of C₃H₈ to moles:

9.6 g C₃H₈ x (1 mol C₃H₈ / molar mass C₃H₈)

Then, use the balanced equation to find the number of moles of CO₂:

moles CO₂ = moles C₃H₈ x (3 mol CO₂ / 1 mol C₃H₈)
