Propane, C3H8, is used as a fuel in many locations. Its unbalanced combustion reaction is as follows:

C3H8 (g) + O2 (g) → CO2 (g) + H2O (l)

If 7.3 moles of propane were to burn in excess oxygen, how many moles of water would be produced?

29.2 mol of water

 

Balanced equation:

C3H8 (g)+ 5O2 (g) → 3CO2 (g) +  4H2O (l)

1 mol of propane burns to give 4 mol of water

So, 7.3 mol of propane will burn to give = 7.3×4 =29.2 mol of water
