No specific procedures were described, and no measurement of the mass of reagent is listed. This reads more like a general description of how to perform the experiment. It does not include any calculations to prove that a 2.00*^-4 M solution with an inherent error of 1% can be produced. The procedure does not outline a beginning value for NaCl. While it does pay attention to steps in the dilution procedures, it fails to account for error in the equipment. First, the person used a dye to mix his or her solution, so it didn't even use the correct solute. However, this person has the right idea of diluting the solutions 3 times to achieve an inherent error of less than 1%.
