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.

What is the difference between atomic mass and mass number?

Atomic mass is also known as atomic weight. Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that element's isotopes. The mass number is a count of the total number of protons and neutrons in an atom's nucleus. The mass number is the sum of the number of protons and neutrons in an atom. It is a whole number.
The atomic mass is the average number of protons and neutrons for all natural isotopes of an element. It is either whole or decimal number.

How to Calculate Atomic Mass?

Atomic Mass calculator uses Atomic Mass = Total Mass of Proton+Total Mass of Neutron to calculate the Atomic Mass, Atomic mass is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes. Atomic Mass is denoted by M symbol.

How to calculate Atomic Mass using this online calculator? To use this online calculator for Atomic Mass, enter Total Mass of Proton (m_p) & Total Mass of Neutron (m_n) and hit the calculate button. Here is how the Atomic Mass calculation can be explained with given input values -> 1.3E+28 = 9.96318000058704E-27+2.65684800015654E-26.

FAQ

What is Atomic Mass?

Atomic mass is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes and is represented as M = m_p+m_n or Atomic Mass = Total Mass of Proton+Total Mass of Neutron. Total Mass of Proton if in Daltons or amu is equal to the number of protons in an atom, else if in kg is 1.67 × 10^(−27) times the number of protons in an atom & Total mass of neutron if in Daltons or amu is equal to the number of neutrons in an atom, else if in kg is 1.67 × 10^(−27) times the number of neutrons in an atom.

How to calculate Atomic Mass?

Atomic mass is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes is calculated using Atomic Mass = Total Mass of Proton+Total Mass of Neutron. To calculate Atomic Mass, you need Total Mass of Proton (m_p) & Total Mass of Neutron (m_n). With our tool, you need to enter the respective value for Total Mass of Proton & Total Mass of Neutron and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
