Describe density.
Explain how to determine the density of an irregularly shaped object such as a mineral sample.
How can density be used to identify an unknown substance?
Answers:1. Density is the amount of stuff or matter packed into an amount of space, for example a golf ball is more dense than a ping pong ball.2. To find the density of a mineral sample, find the volume by using the water displacement method, measure out an amount of water in a graduated cylinder, drop in the sample, measure the final volume, and then subtract the final volume minus the beginning volume to find the volume of the sample. Measure the mass on the triple beam balance, then divide the mass by the volume.4. Certain substances such as minerals and elements have a specific density, by finding the density you can determine the identity of the substance.
