Definition of Density:

Density measures how much matter is in a given volume or the ratio of mass to volume. Density is one of the most important concepts in physics. It is a fundamental concept in science, physics, biology, medicine, and engineering. It can help you understand the relationship between mass, weight, and volume. Density measures how tightly matter is packed together.

To calculate density, divide mass by volume:

Density = Mass / Volume.

For example, a cube with sides 1 meter long (1 cubic meter) weighing 10 kilograms, its density will be 10 kilograms per meter cubed (or kg/m^3).

Units of Density:

Common units of density are as follows. The International System of Units (SI) uses kilogram/meter^3 (kg/m^3). The centimeter-gram-second (CGS) system uses gram/centimter^3 (g/cm^3). The British Imperial and U.S. systems uses slugs/foot^3.

Definition of Mass:

Mass is a measure of how much matter an object contains. Mass is a scalar quantity. It has only magnitude (size), not direction or orientation. The most common units of mass are kilograms (kg) and grams (g). The mass of an object is the resistance to acceleration when a force is applied. The quantity of matter contained within an object also determines its inertia, which measures its resistance to changes in motion.

Note mass is not the same as weight. An object's mass doesn't change when placed on a scale, but its weight does. Weight is the force exerted on an entity by gravity.

Definition of Volume:

Volume is a measure of space occupied by an object. It can be expressed in different units, such as cubic inches or centimeters. For example, the volume of a rectangular solid (such as a cube) is equal to its length times its width times its height:

V = l x w x h

Where l, w, and h represent the dimensions of the object's sides in length, width, and height, respectively.

Is Density the Same as Concentration?

No. Density is a measure of how much space is between molecules. It's also known as mass per volume or molar mass divided by volume.

Concentration measures how much of the material is present in solution or suspension.
