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 = 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 -> 12 = 9.96318000058704E-27+9.96318000058704E-27.
