    How many moles of hydrogen Look at the molar ratio hydrogen to water is 2:2 which is a 1 to 1 molar ratio. This means that for every mole of H2 reacted you have 1 mole of water produced.

    0.253 mol of H2O x (H2/H2O) Multiply by the molar ratio of H2/H20 ensuring that water is I the denominator. And you get 0.253 mol of H2 gas
