Lab 9:  What’s the Concentration of Kool-Aid??? From Amy Rosen Manhattan International High School Purpose: Determine the concentration (molarity) of properly made Kool-Aid. Method: Make three solutions of Kool-Aid with different concentrations and taste them to decide which is the correct concentration. You will prepare 0.1 L of each of the following Kool-Aid solutions: 0.1 M, 0.4 M, and 0.7 M. Materials: Kool-Aid Powder Popsicle sticks (to stir solutions) Water Balance Plastic cups Ruler Procedure: 1. Calculate how much solid Kool-Aid you will need to make 0.1 L of each solution. ( Hint 1: Kool-Aid is mostly sugar (C 6 H 12 O 6 ), so you can assume that the “molar mass” of Kool-Aid is the same as the molar mass of sugar.) (Hint 2: “What you know” is the volume – 0.1 L) Show all of your calculations below. Circle or box the answer for each part. The “molar mass” of Kool-Aid: Mass of Kool-Aid needed for 0.1 M solution: Mass of Kool-Aid needed for 0.4 M solution:

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
