The balanced chemical equation for the reaction of hydrogen and oxygen is shown. 2 cap h sub 2 plus cap o sub 2 rightarrow 2 cap h sub 2 cap o The number of moles of hydrogen that is needed to produce 0 point 2 5 3 mol of water is

The balanced equation shows 2 mol of hydrogen produce 2 mol of water, so the mole ratio of hydrogen to water is 1:1. Therefore, producing 0.253 mol of water requires 0.253 mol of hydrogen, which is equal to 0.253 mol.
