<u>Answer:</u> The mass of carbon dioxide produced is 26.9 kg
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of propane = 9 kg = 9000 g (Conversion factor: 1 kg = 1000 g)
Molar mass of propane = 44.1 g/mol
Putting values in equation 1, we get:
The chemical equation for the combustion of propane follows:
By Stoichiometry of the reaction:
1 mole of propane produces 3 moles of carbon dioxide.
So, 204.08 moles of propane will produce = of carbon dioxide.
Now, calculating the mass of carbon dioxide by using equation 1, we get:
Molar mass of carbon dioxide = 44.01 g/mol
Moles of carbon dioxide = 612.24 moles
Putting values in equation 1, we get:
Hence, the mass of carbon dioxide produced is 26.9 kg
