Help figuring out concentrations please

Procedure Weigh out 500 milligrams each of sugar and undiluted aspartame on a kitchen digital balance if you have one. If you don't have a kitchen digital balance, measure out 1 teaspoon of sugar, which equals 4 grams. Separate that sugar into 8 piles, making them as close to the same size as you can. Each pile is about 500 milligrams. For undiluted aspartame, 1.5 teaspoons is about 500 milligrams. If you don't have undiluted aspartame, you can use sweetener packets, but they are diluted. Each packet has 38.5mg of aspartame in it, so you will need 13 sweetener packets to achieve 500mg (just make sure they are aspartame sweeteners). Place the 500mg of sugar into one cup and the 500mg of aspartame into a second cup. To each add 1 cup of water. Stir each solution until ALL of the sweetener has dissolved (you may need to heat it up a little in the microwave). Once you have both in solution, pour 1/4 cup of each solution into separate cups that will be used for taste testing. This will leave 1/4 cup remaining. To this remaining 1/4 cup, add enough to reach 1 full cup again. Stir the solutions. These second solutions are now 1/4 the concentration of the original solution. You now have a dilution of each sweetener. Pour 3/4 of each dilution into additional cups so that 1/4 cup remains. To this remaining 1/4 cup, add enough water to reach 1 full cup again. You'll now have an even more diluted solution. Continue this process until you have 10 dilutions of the sugar and 10 dilutions of the aspartame. Be sure to label your cups and to arrange them in some logical manner.
