To find the number of moles of water that can be formed, we need to determine the limiting reactant first. The limiting reactant is the reactant that is completely consumed in the reaction, limiting the amount of product formed.
The balanced chemical equation for the formation of water is:
2H₂ + O₂ → 2H₂O
From the equation, we can see that it takes 2 moles of hydrogen gas (H₂) for every mole of oxygen gas (O₂) to produce 2 moles of water (H₂O).
Given that we have 226 moles of H₂ and 108 moles of O₂, we need to compare the number of moles of each reactant to determine the limiting reactant.
For hydrogen gas (H₂):
226 mol of H₂ × (1 mol of O₂ / 2 mol of H₂) = 113 mol of O₂ required
For oxygen gas (O₂):
108 mol of O₂ × (2 mol of H₂ / 1 mol of O₂) = 216 mol of H₂ required
Since we need 113 mol of O₂ but only have 108 mol available, oxygen gas is the limiting reactant.
According to the balanced equation, for every mole of O₂, we can produce 2 moles of H₂O. Therefore, the maximum number of moles of H₂O that can be formed is equal to the number of moles of oxygen gas (the limiting reactant):
Maximum number of moles of H₂O = 108 moles
So, the number of moles of water that can be formed is 108 moles.
