    Amount of sodium sulphate is 5.64g

    Amount of water is 1.017g

    Explanation:

    First give a balanced equation for the reaction

    2NaOH + H2SO4 > Na2SO4 + 2H2O

    Find the number of moles of each reacting specie by dividing the mass by their molar mass

    Use the number of moles to find the amount in the product

    For 2NaOH

    2.26/80=0.02825moles

    0.02825 x molar mass of 2H2O = 1.017g

    For H2SO4

    4.19/98=0.0428moles

    0.0428 x 132 = 5.64g
