    Answer: 2.8 moles

    Explanation:

    The balanced equation below shows that 1 mole of sodium oxide reacts with 1 mole of water to form 2 moles of sodium hydroxide respectively.

    Na2O + H2O - -> 2NaOH

    1 mole of H2O = 2 moles of NaOH

    Let Z moles of H2O = 5.6 mole of NaOH

    To get the value of Z, cross multiply

    5.6 moles x 1 mole = Z x 2 moles

    5.6 = 2Z

    Divide both sides by 2

    5.6/2 = 2Z/2

    2.8 = Z

    Thus, 2.8moles of H2O are needed to produce 5.6 mol of NaOH
