What’s the Perfect Concentration of Kool-Aid?

Calculate how much solid Kool-Aid you will need to make 100 mL of each solution. What is the molar mass of Kool-Aid (C6H12O6)? How many grams of Kool-Aid are needed to make a 0.1 Molarity solution? 0.4 M? 0.7 M?

Questions Which concentration of Kool-Aid did you prefer the most? What was wrong with the other solutions that you made? Calculate the molarity of Kool-Aid as prepared using the directions on the back of the container. The directions read: Add 88 grams (3/4 cup) of Kool-Aid powder to 1 quart (1 quart = 946.35 mL) of water. How is taste related to concentration? Why are they related this way?
