# Problem: Many home barbeques are fueled with propane gas (C3 H8 ).What mass of carbon dioxide (in kg) is produced upon the complete combustion of 18.9 L of propane (approximate contents of one 5-gallon tank)? Assume that the density of the liquid propane in the tank is 0.621 g/mL. (Hint: Begin by writing a balanced equation for the combustion reaction.)

###### FREE Expert Solution

Write the balanced combustion reaction of propane and use stoichiometry to determine the mass of CO2 produced

The combustion of propane or C3H8 will appear as

C3H8 (g) + O2 (g) → CO2 (g) + H2O (g)

C - 3                                C - 1
H - 8                                H - 2
O - 2                                O - 3

The reaction is not yet balanced. Balance C by giving CO2 a cofficient of 3
