A 50.0-mL portion of a solution containing 0.200 g of BaCl2 2H2O is mixed with 50.0

Question:

A 50.0-mL portion of a solution containing 0.200 g of BaCl2 ∙ 2H2O is mixed with 50.0 mL of a solution containing 0.300 g of NaIO3. Assume that the solubility of Ba(IO3)2 in water is negligibly small and calculate
(a) The mass of the precipitated Ba(IO3)2.
(b) The mass of the unreacted compound that remains in solution.
