Answer:
C3H8(g)+5O2(g)→3CO2(g)+4H2O(l)
first calculate the mass of carbon dioxide that can be formed from each reactant mass.
4.41gC3H8×1molC3H844.11gC3H8×3molCO21molC3O2
1molCO2=13.2g

CO2=44.0gCO2
Complete reaction of the propane could produce 13.2 g of carbon dioxide while complete reaction of the oxygen could produce 44.0 g of carbon dioxide, therefore, only 13.2 g of carbon dioxide is formed because there is not enough propane to produce any more carbon dioxide.
13.2 g
