Hi SupraZinc,
Thanks for your question!
You can first calculate the quantity of H2 (n, in moles) that you need to fill the cylinder, with the ideal gas law (PV = nRT) and the data that is given to you in the question.
Then, with stoichiometry, you can determine the quantity of H2O that needs to be used.
Don't hesitate to reach out again if needed:)
