Answer:

Option B. 33 mol

Step-by-step 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.
