Density of Diet vs. Regular Soda
Activity/Procedure
this procedure works best if you use flat soda
- Record the weight of a clean, dry 100mL graduated cylinder. Add exactly 100mL of a regular (non-diet)
soft drink to the cylinder. If you wish, use a dropper to obtain 100mL
exactly. Be sure to read the bottom
of the meniscus, the curvature formed by a liquid in a narrow container
- Weigh the cylinder and beverage. Calculate the density of the regular
soda by dividing the weight of the beverage by 100 mL (the volume of the liquid).
Remember to subtract off the weight of the cylinder.
- Repeat this procedure using a diet soft drink. Compare the density of
the diet and regular soft drinks.
- Explain you results. How could you increase the density of the diet
soft drink? What could you do to decrease the density of the regular beverage?
