A chemist places 2.2352 g of NaCl in a 100 mL volumetric flask and adds water to the mark and calls this stock solution 1. The student then pipets 21 mL of the stock solution 1 into a 50 mL volumetric flask and adds water to the mark and mixes to make solution 2. Then the pipets 15 mL of solution 2 into a 70 mL volumetric flask and dilutes to the mark to make solution 3. Determine the molar concentration of sodium sulfate in solution 3 prepared.
