## What is Atomic Mass?

The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram (kg), the atomic mass is often expressed in the non-SI unit dalton (symbol: Da, or u) where 1 dalton is defined as ​1⁄12 of the mass of a single carbon-12 atom, at rest. The protons and neutrons of the nucleus account for nearly all of the total mass of atoms, with the electrons and nuclear binding energy making minor contributions. In other words, the atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.

## How to Calculate Atomic Mass?

Atomic Mass calculator uses Atomic Mass=Number of Protons+Number of Neutrons+Number of Electrons to calculate the Atomic Mass, Atomic mass is the total of the masses of the electrons, neutrons, and protons in an atom. Atomic Mass and is denoted by M symbol.

How to calculate Atomic Mass using this online calculator? To use this online calculator for Atomic Mass, enter Number of Protons (p+), Number of Neutrons (no) and Number of Electrons (e-) and hit the calculate button. Here is how the Atomic Mass calculation can be explained with given input values -> 18 = 6+6+6.

### FAQ

What is Atomic Mass?
Atomic mass is the total of the masses of the electrons, neutrons, and protons in an atom and is represented as M=p++no+e- or Atomic Mass=Number of Protons+Number of Neutrons+Number of Electrons. The number of protons is the total number of positive subatomic particles found in the nucleus, The number of neutrons is the total number of neutral subatomic particles found in the nucleus and The number of Electrons is the total number of negatively charged subatomic particles which is either free or bound to the nucleus of an atom.
How to calculate Atomic Mass?
Atomic mass is the total of the masses of the electrons, neutrons, and protons in an atom is calculated using Atomic Mass=Number of Protons+Number of Neutrons+Number of Electrons. To calculate Atomic Mass, you need Number of Protons (p+), Number of Neutrons (no) and Number of Electrons (e-). With our tool, you need to enter the respective value for Number of Protons, Number of Neutrons and Number of Electrons and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well. Let Others Know
