    136.5moles of H2O

    Explanation:

    First, let us write a balanced equation for the reaction of Hydrogen to produce water. This is illustrated below:

    2H2 + O2 - > 2H2O

    Molar Mass of H2 = 2x1 = 2g/mol

    Mass of H2 from the question = 273g

    Number of mole = Mass / Molar Mass

    Number of mole of H2 = 273/2 = 136.5moles

    From the equation,

    2moles of H2 produced 2moles of H2O.

    Therefore, 136.5moles of H2 will also produce 136.5moles of H2O.
