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!)

How will you determine the density of an irregular solid like pebbles?
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 in what formula form?
Any unit of mass divided by any unit of volume is a perfectly good unit of density, for any kind of substance.
Is a marble denser than water?
Yes if it floats. Does Marble float in water? If not then the answer is no.
Are All Solids Disolve In Water?
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.
Do amorphous solids have sharp melting points?
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.

What is the average density that are solids?
The average density of solids varies depending on the material. However, the average density of common solids like metals (e.g. iron, aluminum) is around 7,000 to 8,000 kg/m^3. Other materials like wood have lower densities, around 500 to 1,000 kg/m^3.
How do you find the density of a regular shaped solid like a cube?
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.
How do you calculate the density of an irregular shape object such as a rock?
To calculate the density of an irregular object like a rock, you can measure its mass using a scale and then determine its volume using the water displacement method. Once you have the mass and volume, you can divide the mass by the volume to obtain the density of the rock.
What is the expected order of density for matter?
The expected order of density for matter typically follows this general hierarchy: gases have the lowest density, followed by liquids, and then solids, which usually have the highest densities. Among solids, metals generally exhibit higher densities compared to non-metals. Additionally, within specific categories like solids, the density can vary significantly depending on the material's structure and composition.
How do you find the density of an irregular shape solid?
Mass divided by volume, just like anything else.
Does air have a very low density?
Compared to liquids and solids, yes a very low density.
How does dissolved solids affect density?
Dissolved solids increase the density of a solution because they add mass without significantly increasing its volume. When substances like salts or sugars dissolve in a solvent (usually water), they break into ions or molecules, increasing the overall mass of the solution. This change in mass relative to volume results in a higher density compared to the pure solvent. Consequently, solutions with higher concentrations of dissolved solids will generally have greater density than those with fewer dissolved solids.
How do you measure the density of an irregular object like a ball?
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.
If you have an irregular stone about the size of a golf ball outline how to find it s volume?
deep it in water like archemides
What is the difference in finding the density of a rectangular solid object and the density of an irregular solid object?
In finding the density of a rectangular solid object, you can simply calculate it by dividing the mass by the volume using the formula density = mass/volume. However, for an irregular solid object, you may need to use techniques like displacement method or water displacement method to determine its volume before calculating the density.
What can you tell me about the particles in solids?
Particles in solids are closely packed together in a fixed arrangement, which gives solids a definite shape and volume. The particles in solids vibrate in fixed positions but do not move around freely like in liquids or gases. This arrangement of particles in solids gives them high density and strong intermolecular forces.
