    The correct name of the hydrate iron (ii) sulfite is iron (ii) sulfite heptahydrate

    it is gotten as below

    find the % composition of FeSO4 = 100-44.26 = 55.74 %

    find the mole of FeSO4 and H20

    = % composition/molar mass

    FeSo4 = 55.74/151.9 = 0.367 moles

    H2O = 44.26/18 = 2.459 moles

    find the mole ratio by diving each mole with smallest mole

    FeSO4 = 0.367/0.367 = 1

    H2O = 2.459/0.367 = 7

    therefore the name is iron (ii) sulfite heptahydrate is it has seven water molecules
