    Write an balance the equation

    Na2O + H2O - > 2 NaOH

    Calculate the molecular mass of Na2O and NaOH from the atomic mass from the periodic table.

    Na = 23

    O=16

    H=1

    Na2O = 23 * 2 + 16 = 62

    NaOH = 23+16+1 = 40

    For the stoichiometry of the reaction one mole of Na2O = 62g produce two mol of NaOH = 2 * 40 = 80 g

    120 g Na2O x 80g NaOH / 62g Na2O=

    154.8 g NaOH
