Just follow the steps.
To determine the mass of carbon dioxide produced by the combustion of propane, we need to consider the balanced chemical equation for the combustion:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
From the equation, we can see that for every 1 mole of propane (C₃H₈) burned, 3 moles of carbon dioxide (CO₂) are produced.
To calculate the mass of carbon dioxide produced, we'll follow these steps:
Step 1: Convert the given mass of propane (C₃H₈) to moles.
The molar mass of propane is 44.1 g/mol.
50.0 g C₃H₈ x (1 mol C₃H₈ / 44.1 g C₃H₈) = 1.13 mol C₃H₈
Step 2: Use the mole ratio from the balanced equation to find the moles of carbon dioxide (CO₂) produced.
Using the mole ratio: 1 mol C₃H₈ to 3 mol CO₂
1.13 mol C₃H₈ x (3 mol CO₂ / 1 mol C₃H₈) = 3.39 mol CO₂
Step 3: Convert the moles of carbon dioxide (CO₂) to grams.
The molar mass of carbon dioxide is 44.0 g/mol.
3.39 mol CO₂ x (44.0 g CO₂ / 1 mol CO₂) = 149.16 g CO₂ (rounded to two decimal places)
Therefore, the mass of carbon dioxide produced by the combustion of 50.0 g of propane is approximately 149.16 grams.
