3,75 moles barium chloride
4.6 g
Barium nitrate is soluble in water.
This is barium nitrate, an inorganic ionic salt.
Correctly it should be written as 'Ba(NO3)2 ' and it is barium nitrate. Notice the use of brackets and the '2' , to indicate that there are two nitrate anions combined to the one barium cation. NB As you gave it, it does not make sense as a chemical formula.

it is a strong electrolyte because it occurs in strong bases and that's why it is bonded between two different elments
Overall reaction including spectator ions: BaCl2(aq)+K2SO4(aq) --> BaSO4(s)+2KCl(aq) Ionic Reaction: Ba+2(aq) + 2Cl-(aq) + 2K+(aq) + SO4-2(aq) --> BaSO4(s) + 2K+(aq) + 2Cl-(aq) Note that the BaSO4(s) is insoluble. Net Ionic: Ba+2(aq) + SO4-2(aq) --> BaSO4(s) The net ionic equation eliminates the ions that just stay in solution and do not contribute to the precipitate of the barium sulfate.
9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
