🤓 Based on our data, we think this question is relevant for Professor Forster's class at UNLV.
We are asked to calculate the molarity of the solution of the 56.2 mL BaCl2.
BaCl2 + Na2SO4 → BaSO4 + 2 NaCl
Molar mass Na2SO4 = 142.05 g/mol
If 56.2 mL of BaCl2 solution is needed to precipitate all the sulfate ion in a 752 mg sample of Na2SO4, what is the molarity of the solution?
