Reaction equation:

2H₂ + O₂ → 2H₂O

150 moles of Hydrogen requires 75 moles of Oxygen; however, 70 moles of Oxygen are present so Oxygen is the limiting reactant. We will calculate the amount of product using the amount of Oxygen.

Molar ratio of Oxygen : water:

1 : 2

Thus, moles of water = 2 x moles of oxygen

Moles of water = 2 x 70

Moles of water = 140
