The complete dissociation of 8 moles of water produces 4 moles of oxygen.
The moles of reactants and products in the chemical reaction corresponds to the whole number representation of the stoichiometric coefficient in the balanced chemical equation.
The balanced chemical equation for the reaction is:
[tex]\rm 2\;H_2O\;\to\;2\;H_2\;+\;O_2[/tex]
From the balanced chemical equation, dissociation of 2 moles of water produces 1 mole of oxygen.
The moles of oxygen produced by 8 moles of water are:
[tex]\rm 2\;mol\;H_2O=1\;mol\;O_2\\\\8\;mol\;H_2O=\dfrac{1}{2}\;\times\;8\;mol\;O_2\\\\ 8\;mol\;H_2O=4\;mol\;O_2[/tex]
The moles of oxygen produced from 8 moles of water is 4 moles.
