<u>Answer:</u> The correct statement about the complete combustion is 12 moles
<u>Explanation:</u>
We are given:
Moles of propane = 3.00 moles
To calculate the number of moles, we use the equation:
......(1)
For the given chemical equation:
- <u>For carbon dioxide:</u>
By Stoichiometry of the reaction:
1 mole of propane produces 3 moles of carbon dioxide
So, 3.00 moles of propane will produce = of carbon dioxide
Now, calculating the mass of carbon dioxide from equation 1, we get:
Molar mass of carbon dioxide = 44 g/mol
Moles of carbon dioxide = 9 moles
Putting values in equation 1, we get:
By Stoichiometry of the reaction:
1 mole of propane produces 4 moles of water
So, 3.00 moles of propane will produce = of water
Now, calculating the mass of water from equation 1, we get:
Molar mass of water = 18 g/mol
Moles of water = 12 moles
Putting values in equation 1, we get:
Hence, the correct statement about the complete combustion is 12 moles
