Kool-Aid Lab

Kool-Aid Questions
Molarity calculations:
A. Add up the total grams of sugar and kool-aid mix you used and record in your data table. Convert grams of Kool-Aid/Sugar Mix to moles (the gram formula mass for the Kool-Aid/Sugar mix is 342 grams/mol)
B. Convert your volume of solution (145 mL) to liters:
C. Molarity= ____mols solute/ _____L of solution

1. What flavor of Kool-Aid did you use?
2. Describe the taste of your Kool-Aid:
3. What is the Molarity of the Kool-Aid in your cup?
4. What would the Molarity of 2 quarts of Kool-Aid be if you followed the directions on the package?
5. Explain how the recipe for Kool-Aid is like a balanced chemical equation.

charles law is represented by a hot air balloon beacause as the temperature increases so does the volume. and thats what makes the balloon fly. gay lusaacs law is represented in winter wehn your tires are under constant pend the temperature is decreasing so the volume is also. boyles law is represented by peoples ears popping while theyre on an airplane. temperature is constant inside as the plane get higher so does the pressure and the volume of the air inside your eardrums.

Real life Gay-Lussac's Experiment

Real life Charles's Law

Real life example. (Boyle's Law)

Real Life Situations


Boyle's Law: An example that happens in real life is popping your ears on an airplane. When the plane is ascending, it is going from high air pressure to low air pressure. The pressure on the inside of your ears is also building up, causing the volume to increase as well. Popping your ears lets the pressure escape.


Charle's Law: If you blow up a balloon on a cold winters day and then take it outside, it will start to shrivel

up. Then bring it back inside and it will begin to expand again. This is because when the temperature decreases, the balloon becomes less dense, making the volume go down also. The same with increasing the temperature. When the temp. goes up, the balloon gets more dense, making the molecules less concentrated, increasing the volume.






Gay-Lussac's Law: When it is hot outside, sometimes the tires explode because the pressure of the gas inside the tires increases with the temperature. The pressure builds up inside causing it to explode.
