Propane burners are used by campers for cooking purposes while in the wild. What volume of H₂O gas is produced by the complete combustion of 1.8 L of propane (C₃H₈) gas? All gas volumes are measured at the same temperature and pressure.
C₃H₈(g) + 5 O₂(g) $\rightarrow$ 3 CO₂(g) + 4 H₂O(g)

\rightarrow

3 CO₂(g) + 4 H₂O(g)

Quizplus · Accepted Answer

The balanced chemical equation shows that 1 mole of propane (C3H8) reacts with 5 moles of O2 to produce 3 moles of CO2 and 4 moles of H2O. Since all gases are measured at the same temperature and pressure, their volumes are directly proportional to the moles of gas (according to Avogadro's law). Therefore, the complete combustion of 1.8 L of propane will produce 4 times that volume in water vapor, which is 1.8 L x 4 = 7.2 L of H2O gas.
