To calculate the mass of water produced from the reaction, we will use the number of moles of water we found previously, which is approximately 0.916 moles.
1. **Determine the molar mass of water (H2O)**:
The molar mass of H2O is approximately 18.02 g/mol.
2. **Calculate the mass of water from the moles**:
Using the molar mass, we can calculate the mass of water produced:
Mass of water = Moles × Molar Mass = 0.916 moles × 18.02 g/mol ≈ 16.52 g
Therefore, approximately 16.52 grams of water are produced when 5.00 L of propane gas reacts completely with oxygen.
