Ответ:
The mass of carbon dioxide produced is 27.1 grams.
Explanation:
Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.
To calculate the number of moles, we use the equation:
Given mass of butane = 8.9541 g
Molar mass of butane = 58.12 g/mol
Putting values in equation 1, we get:
The chemical equation for the combustion of butane follows:
By Stoichiometry of the reaction:
2 moles of butane produces 8 moles of carbon dioxide
So, 0.154 moles of butane will produce =
of carbon dioxide
Now, calculating the mass of carbon dioxide by using equation 1, we get:
Moles of carbon dioxide = 0.616 moles
Mass of carbon dioxide = 44 g/mol
Putting values in equation 1, we get:
Hence, the mass of carbon dioxide produced is 27.1 grams.
