The definition of dinsity is wieght
The definition of density is: Density = (Mass) divided by (Volume).A simple algebraic operation rearranges this definition to give: Mass = (Density) times (Volume)
You can look up the density of different materials in a table of densities. But if you want a formula, just use the definition of density as mass / volume. This is also how you would measure the density of a substance of unknown density.
The dimensional formula of current density (J) is derived from the definition of current density as current per unit area. Current (I) has a dimensional formula of ([I]), and area (A) has a dimensional formula of ([L^2]). Therefore, the dimensional formula of current density is ([J] = [I][L^{-2}] = [I][L^{-2}]).
Density is defined as the mass divided by the volume. This definition can, in many cases, also be used to measure the density.
Density is calculated by dividing the mass of an object by its volume. The formula for density is: Density = Mass / Volume. This formula allows you to determine how tightly packed the particles in an object are.
Please use the formula: mass = volume x density. (This can be derived by manipulating the definition of density: density = mass / volume.)
Mass density is a measure of how much mass is contained in a given volume of a substance. It is calculated by dividing the mass of an object by its volume. The formula for mass density is: Density Mass / Volume.
Copper has a density of 8920 kg/m3. So 5kg is 0.000565 m3 or 560.5 cm3.======================================Density of copper (look-up) = 8.920 gm/cm3Definition: Density =mass/volumeMultiply each side of the definition formula by (volume): (Volume) x (Density) = (mass) Divide each side by (Density): Volume = (mass)/(density) Volume = 5,000/8.920 = 560.5 cm3 (rounded)
Because that's the man-made definition of "density".
== Density== Mass/ Volume ==
A definition doesn't exist for low density. The values depends on the application or material.
A definition of lower density doesn't exist. Solids with densities under 1,00 g/cm3have a very low density.
