286 (mol BaCl2) * 208.23 (g/mol BaCl2) = 59,553.78 = 59.6*103 g BaCl2 = 59.6 kg BaCl2
FeSO4+BaCl2=>FeCl2+BaSO4
BaCl2 is itself a compound. Its name is barium chloride.
Yes, barium chloride (BaCl2) is soluble in water.

H2S is the chemical formula for barium chloride.
6.022 x 1023 molecules. This is Avogadro's number and a mole of anything. Since there are three atoms in each molecule, one of Barium and two of Chlorine, the number of atoms is three times that, or 1.807 x 1024.
Two atoms of chlorine are needed, one to accept each of the barium electrons in an ionic compound, barium chloride (BaCl2).
FeSO4+BaCl2=>FeCl2+BaSO4
BaCl2 is itself a compound. Its name is barium chloride.

BaCl2+K2CrO4--------->BaCrO4+2KCl BaCrO4 is a yellow precipitate.
Mass of BaCl2 = crucible + lid + BaCl2.nH2O - empty crucible + lidMass of water contained in hydrated BaCl2: Initial mass - final massNo. of moles of H2O in hydrated salt = No. of moles = mass of H2O/formula mass of H2O Use this answer in ratioNo. of moles of BaCl2 in 3.399 g = No. of moles = mass of BaCl2/formula mass of BaCl2 Use this answer in ratioThe ratio of BaCl2 to H2O is 1 : 2
