Answer: 17.91 grams of CO2 will be produced
Step-by-step explanation:
The balanced chemical equation for the combustion of pentane is:
C5H12(l) + 8 O2(g) → 5 CO2(g) + 6 H2O(g)
From the equation, we can see that for every 1 mole of C5H12 that reacts, 5 moles of CO2 are produced. Therefore, to determine the mass of CO2 produced, we need to first calculate the number of moles of CO2 produced by 0.08142 moles of C5H12:
0.08142 moles C5H12 x (5 moles CO2 / 1 mole C5H12) = 0.4071 moles CO2
Now we can use the molar mass of CO2 (44.01 g/mol) to calculate the mass of CO2 produced:
0.4071 moles CO2 x 44.01 g/mol = 17.91 g CO2
Therefore, the mass of CO2 produced by the complete combustion of 0.08142 moles of pentane is 17.91 g.
