Ok, then for each of those formula units, you get one barium+2 and two hydroxide-1 ions, or three ions for each formula unit.

How many moles of ions are released when this sample is dissolved in water?
3.55*10^18 formula units of Ba(OH)2*8H2O?
So far I know to divide this by avogadro's number (/6.022*10^23) which equals .590*10^-5 mol. Don't know what to do from here. Please help!

Ok, so 1.77*10^-5 mol ions?
