The combustion reaction of octane is:
2 C8H18 + 25 O2 = 16 CO2 + 18 H2O
So, the number of oxygen molecules is 25.
The isomer trimethylpentane is used as standard in octane rating: the end of the scale at 100.

When the equation for the complete combustion of one mole of C3H7OH is blanced the coefficient for oxygen is?
The balanced equation for the complete combustion reaction is 2 C3H7OH + 9 O2 -> 6 CO2 + 4 H2O; therefore, the coefficient for oxygen is 9. If fractional coefficients are allowed, the equation can be written with only one mole of C3H7OH; in that instance the coefficient for oxygen would be 9/2.
