Answer : The number of moles of water produced are, 4.4 moles.
Explanation : Given,
Moles of oxygen gas = 2.2 moles
The given chemical reaction is:
By the stoichiometry we can say that, 2 moles of hydrogen gas react with 1 mole of oxygen gas to give 2 moles of water as a product.
From the balanced chemical reaction we conclude that,
As, 1 mole of oxygen gas react to give 2 moles of water.
So, 2.2 mole of oxygen gas react to give moles of water.
Thus, the number of moles of water produced are, 4.4 moles.
