    To find molar mass: look for each element on the table and find their atomic masses. Then add each atomic mass to find the molar mass. If there is a subscript then that means that there is 3 of that number. For atomic mass round to the nearest hundredths

    FeCl3 = 162.2

    Fe2 (SO4) 3 = 354.88

    PbO=223.2

    PbO2 = 239.2

    Pb3O4=685.6
