chromate, 100 grams of barium chloride is mixed with 1050 grams of water to make a barium chloride solution, which has a volume of 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. grams of barium chloride were dissolved in suffcient water to make 2 liters, how many grams of potassium chromate would be required to react completly with all the barium chloride?

BaCl2 + K2CrO4 -> BaCrO4 + 2 KCl
Molar mass of BaCl2 = 208
Molar mass of K2CrO4 = 194.20 g
Calculate molarities and proceed.
