The chemical equation below shows the combustion of propane (c3h8).
c3h8 + 5o2 mc012-1.jpg 3co2 + 4h2o
the molar mass of oxygen gas (o2) is 32.00 g/mol. the molar mass of c3h8 is 44.1 g/mol. what mass of o2, in grams, is required to completely react with 0.025 g c3h8?
a) 0.018
b) 0.034
c) 0.045
d) 0.091

The balanced chemical reaction will be:

C3H8 + 5O2 = 3CO2 +4H2O

We are given the amount of propane gas to be burned. This will be our starting point.

0.025 g C3H8 ( 1 mol C3H8 / 44.1 g C3H8 ) ( 5 mol O2/1 mol C3H8)(32 g O2 / 1 mol O2) =  0.09 g O2
