A solution of Naz2SO4 was prepared by dissolving an unknown mass in distilled water to form 100.00 mL of solution. This solution of Na2SO4 was called as Solution A. The 25.00 mL of Solution A is diluted with distilled water to 50.00 mL. This is solution B. The Solution B is then diluted by a factor of 2 to give Solution C. 15.00 mL of Solution C is added to 25.00 mL of 0.05000 M Na3PO4 to make the Solution D. The concentration of sodium ion in Solution D was found to be 0.1598 M. Calculate the mass of NazSO4 that was dissolved to form Solution A.

So, I don't understand how to calculate concentration for solutions that have been diluted twice. You have W mL of a solution with concentration M. You dilute it to a final volume of X mL.You then pour it out until you're left with Y mL of that diluted solution. Then you dilute what's left to a final volume of Z mL.What's the formula for the final concentration of the solution?
A solution of NazSO4 was prepared by dissolving an unknown mass in distilled water to form 100.00 mL of solution. This solution of NazSO4 was called as Solutlon A. The 25.00 mL of Solution A is diluted vwith distilled water to 50.00 mL. This is solutlon B.
