Answer:
63.9moles
Explanation:
Given parameters:
Number of moles of C₃H₈ = 21.3moles
Unknown parameter:
Number of moles of CO₂ produced = ?
Solution
In order to find the number of moles of carbon dioxide produced we must first write the balanced reaction equation.
This reaction is a combustion of hydrocarbon reaction. It usually occurs in the presence of excess oxygen gas and the product is water and carbon dioxide.
The reaction equation is shown below:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
From the equation:
1 mole of C₃H₈ produced 3 moles of CO₂
Therefore, 21.3 moles of C₃H₈ will produce (21.3 x 3)moles of CO₂
The number of mole of carbon dioxide produced is 63.9moles
