Question

I only need answers for the highlighetd portions.

This was a lab I performed in my chemistry, it was using vaccum filtration to collect solids from a Barium Chloride solution (BaCl2*2H2O). I took 0.780g of Barium Chloride. I added 25ml of water it at first, then transferred it to a 50ml flask and filled it to 50ml and completely mixed the solution. Then I took 38ml of Na3PO4 and mixed it with the 50ml BaCl2 solution into a 250ml beaker. After mixing those, I filtered it out and collected the solids.

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 BaCl,-2H20 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 BaCl, 2H,0.
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.
Considering the volume of barium chloride solution you added to your reaction vessel, how
many moles of barium chloride did you put into your reaction vessel?
