Question dealing with gravimetric analysis lab.

Approximately how many mL of 5% BaCl22H2O solution would be required to precipitate all the sulfate if we assume that your samples are pure sodium sulfate? Assume that the density of the barium chloride solution is 1.00 g/mL.
If the samples were pure potassium sulfate would you require a smaller or larger volume of barium chloride solution than the amount calculated in the previous question?
