Mixture Separation Lab
Your assignment is to take a mixture of BB’s, foam, salt, and sand, and separate it into its
components. After you find the mass of each component, you need to determine the
percent composition of the mixture (what percent is BB’s, foam, etc.).
The mixture will include –
7 mL BB’s
1 scoop foam
5 mL salt
15 mL sand

Actual values
28.48 g BB’s
.11 g Foam
5.96 g Salt
22.27 g Sand
Discussion Questions:
Calculate your percent error for each component.
What step(s) in your method could have led to the errors
you got with the masses of the components?
How would you change your method to prevent these
errors if you did the lab again?
