2.4: Density and its Applications - Chemistry LibreTexts

The general meaning of density is the amount of anything per unit volume. What we conventionally call the "density" is more precisely known as the "mass density". Density can be expressed in any combination of mass and volume units; the most commonly seen units are grams per mL (g mL –1, g cm –3), or kilograms per liter.

density

Definition: Density depends on how atoms or particles are arranged in matter in a specific volume. If the particles are loosely packed together with plenty of space between them, it will have a low density and will be able to float.

Density Definition in Science

Dec 02, 2017 · DENSITY DEFINITION. Density is defined as mass per unit volume. The symbol most commonly used for density is ρ (the lower case Greek letter rho). The capital letter D is also used. Density is an intensive property of matter, which means the size of a sample does not affect its value. Density commonly is expressed in units of grams per milliliter and kilograms per liter.

What is Density? | Chapter 3: Density | Middle School Chemistry

Density is a characteristic property of a substance. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the substance divided by its volume; D = m/v.

Density, mass of a unit volume of a material substance. The formula for density is d = M / V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth 's density is 5.51 grams per cubic centimetre.

Absorbance - Wikipedia

The use of the term "optical density" for absorbance is discouraged. In physics, a closely related quantity called "optical depth" is used instead of absorbance: the natural logarithm of the ratio of incident to transmitted radiant power through a material. The optical depth equals the absorbance times ln(10).

Density - Wikipedia

The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume:

Relative Density Definition in Chemistry

Mar 18, 2019 · Relative density (RD) is the ratio of the density of a substance to the density of water. It is also known as specific gravity (SG). Because it is a ratio, relative density or specific gravity is a unitless value. If its value is less than 1, then the substance is less dense than water and would float.

Density (chemistry) - encyclopedia article - Citizendium

Sep 11, 2013 · Density (symbol: ρ - Greek: rho) is a measure of mass per unit of volume. The higher an object's density, the higher its mass per volume. The density of an object equals its total mass divided by its total volume. An object made of a denser material (such as iron) will have less volume than an equal mass of some less dense substance (such as water).
