Answer:
4.4 moles of water
Explanation:
Propane is C3H8. Is the chemical equation, you wrote C2H8 which is wrong. Type everything properly and give a check before finally posting the question.
The chemical equation that is given, is not properly balanced. The BALANCED equation would be
C3H8 + 5O2 → 3CO2 + 4H2O
From this balanced chemical equation, we see that 5 moles of oxygen produce 4 moles of water.
5 moles of Oxygen → 4 moles of water
1mole of oxygen → moles of water
5.5 moles of oxygen → ( × 5.5) moles of water = 4.4 moles of water
∴ The reaction of 5.5 mol of O2 will produce <u>4.4</u> mol of H2O. [Answer:]
