Should be 19.20 grams of barium hydroxide

mertsj · Answer

Write the balanced equation.

anonymous · Answer

Ba(OH)2 + 2HCl = BaCl2 + 2H2O

mertsj · Answer

The balanced equation says that 1 mole of barium hydroxide is neutralized by 2 moles of hydrochloric acid.  So how many moles of barium hydroxide are you trying to neutralize?

So, assuming that is correct, you need .224 moles HCl.  The solution you are using has .8 moles per liter.  How many liters would you need to give you .224 moles?
