If 22 mol of benzene are completely reacted with molecular oxygen, how many moles of carbon dioxide will be produced?

2C6H6 + 15O2 ==> 12CO2 + 6H2O
Use the coefficients in the balanced equation to convert mols benzene to mols CO2.
That's 32 mol C6H6 x (12 mols CO2/2 mols C6H6) = 32 x (12/2) = ?
To determine the number of moles of carbon dioxide produced when 22 mol of benzene reacts with molecular oxygen, we need to know the balanced chemical equation for the reaction.
The balanced chemical equation for the combustion of benzene with molecular oxygen is:
C₆H₆ + 15O₂ → 6CO₂ + 3H₂O
From the balanced equation, we see that 1 mole of benzene (C₆H₆) produces 6 moles of carbon dioxide (CO₂) when it reacts with 15 moles of oxygen (O₂).
Now, we can use stoichiometry to calculate the moles of carbon dioxide produced when 22 moles of benzene react:
22 mol benzene × (6 mol CO₂ / 1 mol benzene) = 132 mol CO₂
Therefore, when 22 mol of benzene are completely reacted with molecular oxygen, 132 moles of carbon dioxide will be produced.
