In the reaction barium chloride...?

Question

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

Calculate Molar masses of BaCl2 and K2CrO4 and proceed.
