How do you figure out rock Density?

Answer 1

Density is actually a comparison of two things. It's a RATIO. It is a comparison of the mass of something and the volume of that thing. Once we know an object's mass and its volume, we set up a ratio, and that will be the density. Weigh the rock. Put it on a scale. Let's say it weighed 100 grams. Then find its volume. Partially fill a graduated measuring container with water to s fixed level, drop in the rock, and then see how much the water level rose. That will be the volume. Let's say 10 cubic centimeters. Construct your ratio. 100 grams : 10 cubic centimeters We need to refine this a bit so we can make comparisons of the density of one thing to that of another. Let's reduce both measurements by a factor of ten. Dividing both the measurements by ten yields this: 10 grams : 1 cubic centimeter That's ten grams per cubic centimeter for the density of your rock. Grams per cubic centimeter is a common SI expression of the density of a material. If one looked up the density of, say, metals, for example, that's the way they would most likely be found.

Answer 2

you fill a graduated cylander up with water to a certain point. Place the rock in, the water level will rise.Subract the original level of water from the 2nd water level with the rock in it. That is how you find the volume. TO find mass, place rock on electronic, or triple beam balance. Divide the mass by the volume, and that is the density.

Answer 3

Rock density is described as specific gravity, which is the density of the rock relative to the density of water.
