The moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas - b. 4 moles of water

The stoichiometric coefficients can be considered in a balanced equation as moles of reactants needed or moles of products formed in the reaction.  

  • In the given case, the balanced chemical equation for this synthesis reaction looks like this

2H2 + O2 → 2H2O  

  • from the balanced equation, it is clear that the 2  moles of hydrogen gas and 1  mole of oxygen gas are required to produce  2  moles of water.  
  • so it means that the reaction produces twice as many moles of water as you have moles of oxygen gas that take part in the reaction and the same moles as hydrogen atoms present.
  • Here it is given that there are only 2 moles of oxygen which means it is in deficiency however, it will produce 4 moles of water with four moles of hydrogen.

Thus, the moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas - b. 4 moles of water
