Density

To change density there are three ways. You can change the shape, mass or volume of the object

Density of Pebbles = 6.90 g/Cm^3

16.6 g/cc

Density is found when you divide the mass and

the volume.

The crushed can will have a density that is quite a bit higher than the density of the can before it was crushed. Imagine a box of empty aluminum beverage cans. It won't weigh much. If those same cans are crushed, they will weigh the same, but take up a lot less space. The density of the cans can be increased by crushing them. The cans might be said to have a low bulk density before being crushed.

The relative density of a substance is the ratio of its density to the density of some standard substance. The standard substance for solids and liquids is water. Thus for solids or liquids: Relative density = denisty of substance (kg/m3) / density of water (kg/m3) Relative density therefore has no units, it is a number, and indicates only how many times more dense the substance is than water. The relative density of water is 1 or 1000 kg/m3.

• Density of normal concrete is in the order of about 2400 kg. per cubic metre. The densityof light-weight concrete will be less than about density 1900 kg per cubic metre.
  
• The high density concrete have unit weight ranging from about 3360 kg percubic metre to 3840 kg per cubic metre.

you do some multiplication

The density of an any material/object is given by p=m/V

The volume of a cylinder is V= πr2h

So the density of a cylinder is therefore: p=m/πr2h

Where: m is mass, r is radius and h is the height of the cylinder.

The formula for calculating density is as follows: density = mass/volume. Simply put, if you divide an object's mass by its volume, you will find its density. Density is the mass of an object per unit volume.

The density of wood is 650 kg/m3.
That depends on the species of wood. Balsa is very light, D ~ 0.2. Other woods are more dense. Any that float in water have a density less than 1. If it sinks the density is greater than 1.

Density is the mass of the object divided by the volume of the object.

D=m/V

Ether is the common name for the compound, diethyl ether. It has the chemical formula of (C2H5)2O. As a liquid, its density is .7134 grams per cubic centimeter.

The density of tea can vary depending on the type and preparation method. On average, brewed tea has a density of about 1.0 g/cm^3, which is close to the density of water. However, other factors like sugar content, additives, or temperature can affect the density of tea.

Density = Mass/Volume, correct. However, with a cylinder, you have to find the volume. In order to find the volume of a cylinder use the equation PiR2 * H where "R" is the radius (Diameter/2) squared.

mass divided by volume

About 15 to 20 G.

Dissolving salts in water increases the density slightly. Ocean waters have an average density about 2.5% greater than fresh water. The Dead Sea has a much higher density, somewhere roughly near 20% greater than fresh water due to its 30% salinity level.

All else being equal cold water is more dense than warmer water. The Arctic Ocean, being colder, would be more dense.

The population density is 56.3 persons per square mile.

The densest chemical element is the metal osmium (Os) - 22,57 g/cm3.
