Answer:
9.75 mol
Explanation:
2C₄H₁₀ +13O₂ ⟶ 8CO₂+10H₂O
We want to convert moles of C₄H₁₀ to moles of O₂.
Choose the correct conversion factor (the molar ratio).
It is or either (13 mol O₂/2 mol C₄H₁₀) or (2 mol C₄H₁₀/13 mol O₂).
We choose the one with the desired units (mol O₂) on top.
Moles of O₂ = 1.50 mol C₄H₁₀ × 13 mol O₂/2 mol C₄H₁₀
Moles of H₂ = 9.75 mol O₂
