Final answer:
If you react 96 molecules of O2, you can make 96 moles of water molecules.
Step-by-step explanation:
The balanced equation for the reaction is 2H2(g) + O2(g) → 2H2O(l). According to the balanced equation, 2 moles of hydrogen react with 1 mole of oxygen to produce 2 moles of water.
Therefore, if you react 96 molecules of O2, you can make:
(96/2) x 2 = 96 moles of H2O
So, you can make 96 moles of water molecules.
