How do you find density of a mineral sample?
a. What 2 pieces of equipment do you need
b. What are the steps you would follow to find density?
a. You need a mass balance and a graduate cylinder
b. Steps:
You find the mass of the rock
You fill the cylinder with 100 ml of water then drop the rock in
You find the difference between the new volume and 100
You find density= mass divided by volume
400
a Why is density a good property to look at to help identify a mineral?
b. How do you find density?
a. Minerals have very different densities so it is easy to identify one once you find its density
b. density= mass divided by volume
