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.
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
5. Graduated Cylinder
6. 400 mL beaker
7. Bunsen Burner
8. Ring Stand
10. Iron ring
11. Disposable Pipette
12.50 mL beaker
13. Protective goggles
15. Glass rod
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...
