Question

what is mass and density​

Answer 1

Explanation:

The density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume.

Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.

Answer 2

Mass:

• Mass measures the amount of matter in the substance.
• Mass is the amount of matter or substance that makes up an object.

Density:

• Density then shows the amount of matter in a given space for a substance.
• The density, of a substance is its mass per unit volume.
