I only need answers for the highlighetd portions.

Molarity of the barium chloride solution is the number of moles of barium chloride per liter of solution. Recall from the Background section that when BaCl₂·2H₂O dissolves in water, the water from the hydrate separates from the barium ions and chloride ions to become part of the bulk water.

a. Calculate the molar mass of BaCl₂·2H₂O.

b. **Calculate the molarity of the barium chloride solution that you made in your 50.00 mL volumetric flask in lab. In this calculation and all others, remember to keep several significant figures in all your intermediate calculations.**
