Hotdog Lab Report

Purpose: The purpose of this experiment is to determine the amount of fat contained in a hotdog. It will be found in the form of a percentage of the total amount of hotdog used.

Materials:

1. 10.0 grams of finely chopped hotdog meat

2. 250 mL beaker

3. 17 mL of 1.5M NaOH

4. 5 mL of Distilled Water

6. 400 mL beaker

7. Bunsen Burner

8. Ring Stand

9. Tongs

10. Iron ring

11. Disposable Pipette

12.50 mL beaker

13. Protective goggles

14. Aprons

15. Glass rod

16.Triple-Beam Balance

17.Stop watch

18.Dishwashing Soap

19.Spatula

20.Wire gauze

21.Gas

22.Thermometer

23.Thermometer holder

Procedure:

1.First, put on protective goggles and aprons if necessary.

2.Second, weigh and record the weights of the 250 mL and 50 mL beakers.

3. Third, use spatula to obtain approximately 10 grams of finely chopped hotdog meat into a 250 mL beaker and weigh the total mass (Find 10 grams by recording the total mass and subtracting it from the mass of the 250 mL beaker found in step 2).

4.Next, measure 17 mL of 1.5M NaOH in the graduated cylinder and add it to the beaker of hotdog meat.

5.Then, measure 5 mL of distilled water in the graduated cylinder and mix it with the 250 mL beaker of hotdog meat and 1.5M NaOH.

6.Fill a 400 mL beaker about half way full, and place the 250 mL beaker into it, making sure the water does not overflow.

7.Attach the iron ring and thermometer to the ring stand and place the wire gauze on top of the iron ring.

8. Next, place the 400 mL beaker of water and the 250 mL beaker on top of...
