    Now, convert the 74.0 g H2O to grams of H2 using stoichiometry. This answer will be the theoretical (or maximum) yield.

    You'll need to molar mass of the water. Do you know how to find that using the periodic table?

    74.0g H_2O *mole/mass of mole of water *1 mole H_2:1mole H_2O should give you what you need
