<u>Answer: </u>4 moles of are produced.
<u>Explanation:</u>
To calculate the number of moles, we use the formula:
For butane:
Given mass of butane = 58g
Molar mass of butane = 58 g/mol
Putting values in above equation, we get:
For the given chemical equation:
By Stoichiometry of the reaction:
2 moles of butane produces 8 moles of carbon dioxide
So, 1 mole of butane will produce = of carbon dioxide
Hence, 4 moles of are produced.
