A friend has asked you to help the separate a mixture of water and sand. You have carried out the experiment. Write a laboratory report to share your findings. Include the following: date, title, aim, materials

see below

Explanation:

9/14/2021 (insert experiment name) to try and separate water and sand

Materials

-A fine metal strainer

-cheese cloth

-2 large size bowls

-scissors

Take a large bowls prop strainer up on the mouth of it then cut cheese to fit in the strainer pour sand water into strainer after done take the cheese cloth and squeezed then put sand into other bowl

law of conservation of matter

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
