Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V. In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. The standard SI unit is kilograms per cubic meter ( kg/m3 ).

The polymorphs diamond and graphite are both made of carbon (C), but due to differences in atomic arrangements, diamond has density of 3.5 gm/cm 3, while graphite’s is 2.2 gm/cm 3. Graphite forms under Earth surface conditions, but diamond, with its high density, only forms deep in Earth where pressures are great.

· ρ = Density = kg/m3. m = Mass = kg. V = Volume = m3. So drop the numbers of your measurements into the equation: ρ = 5400kg ÷ 2m3. and the answer is. ρ = 2700kg/m3. Aluminium has a density of approx 2705kg/m 3 and Stainless Steel has a density of approx 7982kg/m 3. So the block must be made from Aluminium.

· The density (⍴) of any substance is the reciprocal of its specific volume (ν). ρ = m/V = 1/ν. The specific volume (ν) of a substance is the total volume (V) of that substance divided by the total mass (m) of that substance (volume per unit mass). It has units of cubic meter per kilogram (m 3 /kg). See also: Supercritical Fluid.

Definition. Density is the measure of how much “stuff” is in a given amount of space. For example, a block of the heavier element lead (Pb) will be denser than the softer, lighter element gold (Au). A block of Styrofoam is less dense than a brick. It is defined as mass per unit volume. You can therefore think of it as how tightly or loosely

Updated on January 15, 2020. Specific gravity is the ratio of the density of a substance to the density of a reference substance, which is usually water for liquids and air for gases. When water is used, it is at its highest density, which is at 4 °C or 39.2 °F. When air is used, it is most often room temperature air, at 20 °C or 68 °F.
