    Given that the 2 products of combustion are CO2 and H2O, I count 5 O2’s to balance that equation.

    C3H8 + 5O2 => 3CO2 + 4H2O

    this is a combustion reaction;

    C3H8 + 5O2 –> 3CO2 + 4H2O

    According to the balanced reaction equation given above, the mole ratio between O2 and C3H8 is 5:1
    Thus, 5 moles of O2 should be supplied to burn 1 mole of C3H8

    hope this helps:-) kodie
