Atomic mass - Wikipedia.

The atomic mass (m a or m) is the mass of an atom.Although the SI unit of mass is the kilogram (symbol: kg), atomic mass is often expressed in the non-SI unit dalton (symbol: Da) - equivalently, unified atomic mass unit (u). 1 Da is defined as 1 / 12 of the mass of a free carbon-12 atom at rest in its ground state. The protons and neutrons of the nucleus account for nearly all of the total ....!&&p=6bd20d1922e5f0daJmltdHM9MTY2MDU2NTQwMSZpZ3VpZD0yMjU1MjUyOC1kNTE1LTQ4MDEtODIyMi00NWRmOTU3YTFiZGMmaW5zaWQ9NTExNA&ptn=3&hsh=3&fclid=300888de-1c93-11ed-9985-e19a904ac7a4&u=a1aHR0cHM6Ly9lbi53aWtpcGVkaWEub3JnL3dpa2kvQXRvbWljX21hc3M&ntb=1.

Relative atomic mass - Simple English Wikipedia, the free ….

A relative atomic mass (also called atomic weight; symbol: A r) is a measure of how heavy atoms are. It is the ratio of the average mass per atom of an element from a given sample to 1/12 the mass of a carbon-12 atom. In other words, a relative atomic mass tells you the number of times an average atom of an element from a given sample is heavier than one-twelfth of an atom of ....!&&p=344615d2f9572a51JmltdHM9MTY2MDU2NTQwMSZpZ3VpZD0yMjU1MjUyOC1kNTE1LTQ4MDEtODIyMi00NWRmOTU3YTFiZGMmaW5zaWQ9NTEzMg&ptn=3&hsh=3&fclid=30089a60-1c93-11ed-a4d4-25572a5eeca3&u=a1aHR0cHM6Ly9zaW1wbGUud2lraXBlZGlhLm9yZy93aWtpL1JlbGF0aXZlX2F0b21pY19tYXNz&ntb=1.
