You can use Calculus to figure it out, but that's a lot of work.
A more simple approach is to:
# mass it (in grams)
# dunk it into a pitcher of water, and record how much liquid it displaces (in mL = cm^3)
# take (1), divide (2) # if the number is less than 1 it floats, and if the number is greater than 1 it sinks
Explanation:
* Density is defined as mass/volume, so to figure out the density of an object, find it's mass and it's volume, and divide the two. * To mass something is kind of like weighing it, but with different units. If something weighs 1 pound it's mass might be about 450 grams, depending on where you are. * An easy home-approach to finding volume of ex. a rock would be to find how much liquid it displaces. Take a measuring beaker that measures mL and fill it with ex. 500 mL of water, then insert your rock. Let's say the water level rose to 550 mL, that means your rock's volume is 50 mL. 1 mL = 1 cm^3 * So lets say your rock weighed 150 grams (about 5 ounces), and the water moved up 50 cm^3, so the rock's mass is 150g/50cm^3 = 3 g/cm^3 * Water's density is about 1 g/cm^3, so this rock's density is about 3 times as much as water! (I guess we just proved why rocks don't float!)

∙ 14y agoThe density of irregular solids like stone can be determined by measuring the mass and volume of the object. The density formula is density = mass/volume. To find the volume of an irregular solid, displacement method or water displacement method can be used.

∙ 9y agoThe density of rock depends on the type of rock. Among common rock types density can vary from 2.2 grams per cubic centimeter for porous sedimentary rock to 3.4 grams per cubic centimeter for ultramafic igneous rock.

You have to fill a measuring cylinder with water. There is no fixed position were you stop. Read at eye level at the bottom of the meniscus (Vol. 1). Put the irregular object in the water and again, read the water at eye level at the bottom of the meniscus (Vol.2).Subtract (Vol.1) from (Vol.2).
That is the volume of the irregular object. For the density:
density=mass
---------
Volume
Calculate it and you have the answer.

To determine the density of irregular solids like pebbles, you can use the water displacement method. First, measure the volume of water in a container. Then, add the irregular solid to the water and measure the new volume. The difference in the two volume readings can be used to calculate the volume of the irregular solid. Finally, divide the mass of the pebbles by the volume to calculate the density.
The density of solids and liquids is generally expressed as mass divided by volume, in the formula: density = mass / volume. It is typically measured in units like g/cm^3 or kg/m^3.
Yes if it floats. Does Marble float in water? If not then the answer is no.
Not all solids dissolve in water. Solubility depends on the chemical structure of the solid and its interaction with water molecules. Solids like sugar and salt are considered soluble in water, while substances like sand and oil are insoluble.
No, amorphous solids do not have sharp melting points like crystalline solids. Instead, amorphous solids soften over a range of temperatures as they transition into a more fluid state, making their melting behavior less well-defined.

No, because stone like solid are unmelted.
Since mass is usually expressed in grams and volume in cubic centimeters, density is expressed in grams/cubic centimeter. For solids that have an irregular shape, the displacement method must be used to determine their volume. Choose a graduated cylinder large enough to hold the object.
Mass divided by volume, just like anything else.
There are many types density, like true density, tap density, bulk density etc. Can use analyzer like G-DenPyc 2900 gas pycnometer analyzer to measure them. Aerometer or Hydrometer for density of liquids, Dasymeter for density of gases and Resonant Frequency and Damping Analyser (RFDA) for density of solids.

deep it in water like archemides
The volumes of small irregular solids are usually easily measured by measuring the volume of fluid displaced when they are immersed in a liquid. For example: You would have to put the object in a measuring glass with water in it. (~1/3 filled) Put the object in it and then get the number from the measuring glass (beaker etc. mostly beaker) and that is how you measure a irregular solid!
You can measure the density of an irregular object, like a ball, by determining its mass using a scale and then measuring its volume by either water displacement or geometric calculations. By dividing the mass of the object by its volume, you can calculate its density.
In general, a rise in temperature causes solids to expand and become less dense, as the particles vibrate more and spread further apart. Liquids, on the other hand, generally become less dense as they warm up, because the increased energy causes the particles to move more freely and thus take up more space.
Ice, like other solids will expand with heat. It has a coefficient of expansion of 50 ppm/°C. So, the colder the ice is, the smaller, and higher density it will be. The warmer, the lower the density, with the maximum temperature (and lowest density) being at the melting/freezing point.
Bulk density is a mainly a property of powders, granules and other separated solids, usually used in minerals like soil or gravel. It is defined as the total amount of particles over the total volume they occupy.
