Answer:
            Mole ratio of Carbon dioxide to Propane  is;

                                                3  :  1
Explanation:

The Balance Chemical Equation is as follow,

                                 C₃H₈  +  5 O₂    →    3 CO₂  +  4 H₂O

According to equation, 1 mole of propane reacts with five moles of Oxygen gas to produce three moles of Carbon dioxide and four moles of Water. Therefore, the mole ratio of all reactants and products can be written as,

                                              1  :  5  :  3  :  4

Where;
            1  =  C₃H₈

            5  =  O₂
  
            3  =  CO₂

            4  =  H₂O
