To burn 1 molecule of C7H16 to form CO2 and H2O (complete combustion), how many molecules of O2 are required?
- Roger the MoleLv 71 month ago
C7H16 + 11 O2 → 7 CO2 + 8 H2O
11 molecules of O2 are required.
billrussell42: It doesn't matter if it is heptane or not. The given formula answers the question unambiguously.

assuming that is heptane
heptane + Oxygen ➜ Carbon Dioxide + water
balanced equation is:
C₇H₁₆ + 11 O₂ → 7 CO₂ + 8 H₂O
11 molecules of O₂ combine with 1 molecule of C₇H₁₆
