Density
Density is mass per unit of volume. Density also shows how tightly packed in molecules are in a material and also help determine buoyancy.

How does salinity affect the density of the ocean water?
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.
Which is probably denser the water in the Arctic Ocean or the water in the Caribbean sea?
All else being equal cold water is more dense than warmer water. The Arctic Ocean, being colder, would be more dense.
What is the density of seawater?

Which naturally occurring element has the highest density?
The densest chemical element is the metal osmium (Os) - 22,57 g/cm3.
What is the density of a 24g mass of a substrance that has volume of 8cm cubed?
The substance's density is 0.11 g/cm3
The density of butane is approximately 0.58 grams per cubic centimeter at 25°C (77°F) and atmospheric pressure.
What is the density of volume 144L and mass 129.6kg?
The density of any object is equal to its mass divided by its volume. At a mass of 129.6 kilograms and a volume of 144 liters, the substance has a density of .9 kilograms per liter.
How do you find density from grams?
Density is calculated by dividing the mass (in grams) of a substance by its volume (in milliliters or cubic centimeters). The formula for density is: Density = Mass / Volume. By measuring the mass of a sample in grams and the volume in milliliters, you can easily calculate the density of the substance.
Since chert is made of SiO2, its density should be 2.65 which is the same for quartz (SiO2). However there some exceptions to the density value of 2.65 being attributed to SiO2. The density of 2.65 attributed to Quartz is when it exists in the most common trigonal crystalline form. Chalcedony a form of quartz known as cryptocrystalline quartz including chert, flint and agates including Jasper, has minute crystals of quartz with submicrospcopic pores. Flint has about 1% water included within it and a density that varies from 2.57 to 2.64. Other variations of quartz can be formed in an orthorhombic crystal form (Trydymite) with a density of 2.26 or a tetragonal crystal form (Christobalite) that has a corresponding density of 2.33.

Something that which produces a magnetic field
The magnetic field that surrounds a magnet is made up of magnetic flux (symbol, the Greek letter 'phi'), usually represented as lines in field diagrams. The SI unit for measuring magnetic flux is the weber (pronounced 'vay-ber'). The intensity of this flux (the closeness of the lines in diagrams) is called the flux density (symbol: B). Flux density is greatest in the areas nearest a magnet's poles. Flux Density is defined as 'flux per unit area', and is measured in webers per square metre which, in SI, is given the special name, the 'tesla'.
What would the density of the cube above be if the mass was 700 grams?
The weight of 700 grams of mass is:
-- 6.86 N (1.543 pounds) on earth
-- 1.12 N (4.03 ounces) on the Moon
-- 2.604 N (9.38 ounces) on Mars
-- 0.408 N (0.86 ounce) on Pluto
-- 18.1 N (4.08 pounds) on Jupiter
Current density is the amount of electrical current flowing in a unit of cross sectional area of that conductor. You'd look at the current flowing and the cross sectional area of the conductor and make a calculation from that. All you need do is decide on what unit of cross sectional area you wish to use. In wire, we usually use mils. Use the links below for more information.
Density current is the measure of the density of flow of a conserved charge
What is the density of a object with a mass of 90 grams and a volume of 30 centimeters?
Volume cannot be measured in centimetres. Without the volume in appropriate units, the question makes no sense and so cannot be answered.
No. Just because two liquids have the same volume they do not have the same density. A liter of mercury is denser than a liter of water.
However, if two liquids of the same volume have the same mass as well, then they have the same density.
It depends on which polyamide. Try rephrasing the question.
What is the density of a block of metal with a mass of 10g and a volume of 2ml?
The density (ρ) equals the mass (m) divided by the volume (V).
ρ = m/V
Since the block you have is a square, we can say that it's width and height equals his length, which is 2 millimeters.
The volume of your block is 0.002³ meters (width x lenght x height) = 0.000,000,008 cubicle meters (or 8 cubicle millimeters).
Since the mass is 10 grams (0.010 kilos), your density is 10 grams per 8 cubicle millimeters (or 0.010 kg / 0.000,000,008 cubicle meters)
So ρ = 10 grams / 8 cubicle millimeters
What is the density of a substance with a mass of 0.0450 kg and a volume of 26.4 mL?
The substance has a density of about 1.704 g/mL
The SI unit is kilogram per cubic meter. However, in practice, kilogram per liter, or the equivalent gram per cubic centimeter, is also often used. This latter gives numbers that are a thousand times smaller; for example, the density of water is about a thousand kilograms per cubic meter, or one kilogram per liter.
How do you find the density of a block?
it is easy. You use Mass divided by Volume. You can Remember it by a heart. The top is a M and the bottom is a V. Mass divided by volume. <3
It is 1.07 gm/cc for amorphous type..
and 1.25 gm/cc for crystalline.
Arithmetic density is the total number of people divided by the total land area
it like this the total population divided by the total land area that is cultivated or in simple TP/TLA
It's important because knowing the population and the land that they are inhibiting could help knowing how many towns, or city's they can build for the population in the future. If the land is overpopulated, they would need to find a way to take all those people and fit them in. Also, Knowing how many people take up the land can determine how much agricultural density is needed for the people there or in other places. Normally, when land is overpopulated, more people will want to move there. So knowing the population would prepare them for immigrants to come into the area. Hope this helped.
