If a student burns 3.53 moles of C3H8, 10.29 moles of carbon dioxide would be produced. Details about number of moles can be found below.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated as follows:
The following chemical equation was given as follows:
C3H8 + 502 = 3CO2 + 4H₂O
1 mole of C3H8 produced 3 moles of carbon dioxide
Hence, 3.53 moles of C3H8 will produce 3.53 × 3 = 10.59 moles of CO2.
Therefore, if a student burns 3.53 moles of C3H8, 10.29 moles of carbon dioxide would be produced.
