Sugar Density Lab

Lab Partners: Hannah, Kellie, Chandler
Title
Sugar Content in Beverages
Date
Date Started- 8/28/13
Date Finished- 8/28/13
Purpose
To test the density of sugar in a beverage
Equipment
300mL beaker
250mL beaker
100mL graduated cylinder
Celsius thermometer
Metric Balance
Procedure
1) Place a clean 100mL graduated cylinder on the balance and hit the “rezero” button.
2) Fill the cylinder to the 10mL mark with a beverage. Measure and record the mass of the beverage in the graduated cylinder.
3) Measure and record the temperature of the beverage.
4) Rezero the balance with the graduated cylinder containing the beverage. Fill the graduated cylinder to the 20mL mark with a second sample of the same beverage. Measure and record the mass of the beverage sample in the graduated cylinder.
5) Calculate and record the density of each beverage sample.

Data

Volume | w/beaker weight | w/o beaker weight | Density Formula | Density | Percent Sugar | 10mL | 65.56g | 9.85g | 9.85g/10mL | .925g/mL | 17% | 20mL | 75.75g | 20.04g | 20.04g/20mL | 1.002g/mL | 12% | 30mL | 86.85g | 31.14g | 31.14g/30mL | 1.038g/mL | 10% | 40mL | 96.63g | 40.92g | 40.92g/40mL | 1.023g/mL | 10% | 50mL | 106.33g | 50.62g | 50.62g/50mL | 1.012g/mL | 5% |

Calculations and Graphs

Conclusions
Seemingly healthy drinks can have high sugar contents.
Discussion of Theory
This experiment worked on the idea of density.
Experimental Sources of Error
-Graduated cylinder not accurate enough
-Miscalculated
