Answer:
Option B. 33 mol
Explanation:
The balanced equation for the reaction is given below:
2C₄H₁₀ + 13O₂ —> 8CO₂ + 10H₂O
From the balanced equation above,
2 moles of C₄H₁₀ reacted with 13 moles of O₂.
Finally, we shall determine the number of mole of oxygen, O₂ required to react completely with 5 moles of butane, C₄H₁₀. This can be obtained as follow:
From the balanced equation above,
2 moles of C₄H₁₀ reacted with 13 moles of O₂.
Therefore, 5 moles of C₄H₁₀ will react with = (5 × 13)/2 = 33 moles of O₂.
Thus, 33 moles of oxygen, O₂ is needed for the reaction.
