Answer:
When propane gas (C3H8) is burned in the presence of oxygen, it produces carbon dioxide (CO2) and water (H2O) according to the following balanced chemical equation:
C3H8 + 5O2 → 3CO2 + 4H2O
The equation shows that for every 1 mole of propane burned, 4 moles of water are produced.
Therefore, if 1.14 moles of CO2 are produced, it means that 1.14/3 = 0.38 moles of propane were burned.
Since each mole of propane burned produces 4 moles of water, the total number of moles of water produced is 4 x 0.38 = 1.52 moles.
Therefore, 1.52 moles of water (H2O) are made when 1.14 moles of CO2 are produced by burning propane gas.
