Look at the balanced equation below: C2H6O + 3 O2 → 2 CO2 + 3 H2O

If you produced 11.5 moles of H2O, how many moles of O2 were used?

11.5 moles O2
11.5 moles O, 2

34.5 moles O2
34.5 moles O, 2

3.83 moles O2
3.83 moles O, 2

7.67 moles O2

11.5moles of oxygen gas

Explanation:

The reaction equation is shown below;

     C₂H₆O  + 3O₂ → 2CO₂  +  3H₂O

 We were given  11.5moles of H₂O produced;

Since the equation is balanced;

          3 mole of oxygen gas was used to produce 3 mole of water

        11.5 moles of water will be produced   = 11.5moles of oxygen gas
