Density is a specific property, so we can use it to identify different substances. There is the protocole:

1. Weigh the 10 mL graduated cylinder empty
2. Press "Tare" key.
3. Fill the graduated cylinder with 10 mL
4. Weigh it again
5. Calcule the density
6. Repeat all the process with a 25 mL graduated cylinder.
7. Repeat all the process with a 50 mL graduated cylinder.
