Final answer:
The coefficient for oxygen in the balanced equation for the combustion of one mole of C3H7OH is 4.
Step-by-step explanation:
The coefficient for oxygen in the balanced equation for the complete combustion of one mole of C3H7OH is 4.
The balanced equation is: C3H7OH + 4O2 → 3CO2 + 4H2O
This means that 4 moles of oxygen are required to completely burn one mole of C3H7OH.
