What is mass in chemistry?

Answer 1

Mass is a measurement of how much matter there is in a body.

.

In classical physics, mass is generally described as either inertial mass or gravitational mass, which for all common purposes, are the same. Inertial mass (which leads to momentum) is a measurement of a body's resistance to a change in velocity when an external force is applied to that body. Gravitational mass (which leads to weight) is the magnitude of a body's interaction with a known gravitational field.

.

In relative physics, mass has two components: the classical mass, described above, also known as rest mass (or invariant mass), and relativistic mass. A body's rest mass remains constant, and its relativistic mass is zero when the the body is not moving (i.e., at rest). A body's relativistic mass increases as the body's velocity approaches the speed of light. Relativistic mass does not become significant until the body's velocity exceeds 1/10th the speed of light (0.1c). At 0.1c, the body's mass is 1.005 times its rest mass, meaning the relativistic mass is 0.5% of the rest mass. At 0.86c, relativistic mass equals rest mass, meaning the body's mass is twice its rest mass. It should be noted that the body's effective inertial mass is twice the rest mass at 0.86c - meaning it has twice the momentum it would have if the body had rest mass alone. In other words, the body in motion at 0.86c is twice as hard to speed up, slow down, or change direction than if it had had only rest mass. The relativistic mass increases asymptocically to infinity as the body's velocity approaches the speed of light.

.

In quantum physics, mass can be described as the amount of potential energy contained within a body, and is a measurement of how much energy would be liberated should that mass be converted into energy through mass annihilation using the famous E=mc2 equation.

It could also mean church.
the density or volume of matter

Answer 2

To found out the mass, the Mole formula is used.

The mole formula is given as n = m/M

Rearranging the equation gives us the following: m = nM

Therefore, you multiply the number of moles (n) by the molar mass (M).

Answer 3

The word mass has many different meanings.

Mass (noun) - a large body of matter

Mass (adjective) - affecting a large number of people

Mass (verb) - to assemble as one group or large body

Answer 4

Mass in chemistry refers to the amount of matter an object contains. It is typically measured in grams or kilograms. Mass is an extensive property, meaning it depends on the amount of substance present.

Answer 5

A mass is a form of prayer to get closer to god. It is also the weight or size of something.

Answer 6

Are you referring to relative Atomic Mass, such as in elements? This information is available on the Periodic Table of the elements. Mass has weight and occupies space.

Answer 7

Mass is the amount of matter in an object.

Answer 8

Mass in Biology is a body of coherent matter, usually does not have any indefinite shape. It can also be a collection of incoherent particles.
