Consider the balanced equation for the combustion of benzene, C₆H₆.
2 C₆H₆ + 15 O₂ —+12 CO₂ + 6H₂O
What molar ratio will appear when calculating the amount of O₂ needed to react with a given amount of C₆H₆?
O 1 mol O₂ ÷ 1 mol C₆H₆
O 12 mol CO₂ ÷ 2 mol C₆H₆
O 15 mol O₂ ÷ 2 mol C₆H₆
O 12 mol O₂ ÷ 2 mol C₆H₆
