Amount (in grams) of oxygen required for the complete combustion of 2 moles of benzene is
The balanced reaction for combustion of benzene is :
2C6H6+15O2→ 12CO2+6H2O
Therefore, 15 moles of oxygen gas is required for the complete combustion of benzene.
We know that, 1 mole of O2 = 32g
∴ 15 moles of O2 = 15 × 32 = 480g
