# Problem: The combustion of propane may be described by the chemical equation C3H8(g)+5 O2(g)⟶3CO2(g)+4H2O(g) How many grams of O2(g) are needed to completely burn 86.6 g C3H8(g)?

###### FREE Expert Solution

We are being asked to determine the mass of O2(g) needed to completely burn 86.8 g of C3H8(g). We are given the balanced chemical equation for the combustion of propane

C3H8(g)+5 O2(g)⟶3CO2(g)+4H2O(g)

The flow of the solution is

mass C3H8(g) (molar mass C3H8(g) ⟶ mole C3H8(g) (mole-to-mole comparison) ⟶ mole O2(g) (molar mass O2(g)) ⟶ mass O2(g)
