    Mass of Na2SO4 = 80.5g
    Molar mass of Na2SO4 = 14.2g/mole

    Asked
    To calculate mole of BaSO4.
    Equation
    Na2SO4(aq) +Ba(NO3)2(aq) →BaSo4(s) + 2 NaNo3(aq)

    To convert mass of Na2SO4 into moles
    Mole of Na2SO4 = mass / Molar mass
    = 80.5g / 142g/mole
    = 0.5669 mole of Na2SO4

    To make mole equivalent
    1 mole of Na2SO4 Ξ 1 mole of BaSo4
    0.5669 mole Na2SO4 Ξ?? X

    X = (0.5669 mole × 1 mole) / 1 mole
    = 0.5669 mole

    Mole of barium Sulphate (BaSo4) were 0.5669 mole
