Beverage Density and Sugar Content

Question:

Why does an unopened Coke can sink but an unopened Diet Coke can float?

Background Information:

Fat, sugar, and salt are three food components that most Americans consume in excess. Almost all soft drinks that are not milk-based (Coke, Sprite, Kool-aid, Gatorade, etc.) are essentially sugar solutions with small amounts of additives for flavoring and color. This means the sugar would be dissolved in 95 grams of water. Since water has a density of 1.00 g/mL, this would be 95 mL of water.

Procedures:

1. Read the labels of three soft drinks and/or fruit juices in your home or the store. Record the name of the soft drink or fruit juice, size of serving and grams of sugar per serving on your constructed table.

2. How would the sugar content of a solution impact the solution’s density? Explain.

3. Which of your drinks would you predict to have the highest density? Explain.

4. How would you make a 20% sugar solution?

5. Measure and record the mass and volume of 0%, 5%, 10%, 15%, and 20 % sucrose solution.

a. Place your solution on a bathroom scale. You will add all your solution
