Reaction between Barium Chloride and Potassium Chromate?

Question

In the reaction barium chloride plus potassium chromate yields potassium chloride and barium chromate, 100 grams of barium chloride is mixed with 1050 grams of water to make a barium chloride solution, which has a volume exactly 1000 mL. It is titrated with a solution of 100 grams of potassium chromate dissolved in sufficient water to make exactly 5000 mL of solution.

Calculate the following:
A.) The mass percent of the barium chloride.
B.) The molarity of the potassium chromate solution.
C.) The volume of potassium chromate solution required to react with all the barium chloride solution.
D.) If 200 gramso f barium chloride were dissolved in sufficient water to make 2 liters, how many grams of potassium chromate would be required to react completely with all the barium chloride?

Answer 1

BaCl2 + K2CrO4 -> BaCrO4 + 2 KCl

Molar mass of KCl = 74.5 g

Molar mass of BaCrO4 = 253 g

Now calculate the molarities.
