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.
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.

Population density of Canada?
Is the population density in Canada?
What are three types of rock formations explain how each of the three is formed?
the three rocks are igneous ,metamorphic and sedimentary i don't know what it is made up of but that is what i trying to figure out can someone help me please
What is the density of mineral apatite?
Its density is: 3.19
What mineral has the density of about 10.5?
That would be Silver, with a density of exactly 10.5Also, Sperrylite, with a density of 10.58
Mass of rock?
Mass is measured by density multiplied by volume. In order to figure out a mass of a rock, one must know its density and its volume measurements.
If a rock had the mass of 25.1 g and volume of 3 ml What is the density of the rock?
The density of the rock can be calculated by dividing its mass by its volume. In this case, the density of the rock would be 25.1 g / 3 ml = 8.37 g/ml.
What is the density of a rock that has a mass of 96.2 grams?
there is not enough information to figure this one out, You need the volume (or if you know the elements its made out of , you can figure it out through molar mass)
If you have two rocks rock A and rock B Rock A is bigger but has the same mass as rock B How will the density of the two rocks compare?
Since rock A is bigger but has the same mass as rock B, it will have a lower density compared to rock B. Density is calculated by dividing mass by volume, so the larger volume of rock A will result in a lower density.
Which has more density a rock or pillow?
A rock
How rock density affect the formation of war the layers?
Rock density has no direct affect on war.
If you have a rock with a volume of 15cm3 and a mass of 45g What is its density?
The rock's density is 3 g/cm3
What is the average density of Pluto?
The average density of Pluto is estimated to be around 1.86 grams per cubic centimeter. This indicates that Pluto is composed mainly of rock and ice.
What is the density of a rock with a mass of 12g and a volume of Cm?
To calculate density, you need to divide the mass of the rock by its volume. In this case, the density of the rock would be 12g divided by its volume in cm^3. Without knowing the volume in cm^3, it is not possible to determine the density of the rock.
A rock has a mass of 127grams and displaces 32.1 mL of water What is the density of the rock?
The density of the rock can be calculated by dividing the mass of the rock (127g) by the volume of water it displaces (32.1 mL). The density of the rock is 3.95 g/mL.
If a rock has a volume of 13 cm 3 and a mass of 130grams what is its density?
The rock has a density of 10 g/cm3
What happens to the density of rock as it cools?
As rock cools, its density increases. This is because cooling causes the atoms and molecules to arrange themselves in a more compact and ordered manner, leading to an increase in the density of the rock.
