Question

What is the molar ratio for the following equation after it has been properly balanced?
____C3H8 + ____O2 Imported Asset ____CO2 + ____ H2O

Reactants: C3H8 = 2, O2 = 5; Products: CO2 = 6 and H2O = 4

Reactants: C3H8 = 1, O2 = 5; Products: CO2 = 3 and H2O = 4

Reactants: C3H8 = 1, O2 = 8; Products: CO2 = 3 and H2O = 4

Reactants: C3H8 = 1, O2 = 5; Products: CO2 = 3 and H2O = 5

Answer 1

the answer 
the molar ratio for the following equation 
____C3H8 + ____O2 Imported Asset ____CO2 + ____ H2O

after it has been properly balanced:
__1_C3H8 + ____5O2 Imported Asset ____3CO2 + ____ 4H2O

proof:
number of C =3  (C3H8;   3CO2)
number of H =8 (C3H8 ; 4H2O)
number of O = 10(5x2) or (2x3+4)  (5O2;4H2O)

the answer is 
Reactants: C3H8 = 1, O2 = 8; Products: CO2 = 3 and H2O = 4
