Atomic mass units
Cobalt is an atomic mass of 58.93 atomic mass units
The atomic mass of astatine is 209.9871 atomic mass units (amu). The atomic mass is given for the longest lived isotope of astatine, which is astatine-210, with a half life of 8.3 hours.
Atomic mass is so small you can't actually measure it. So, just like carbon dating, you have to use a relative mass.
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in atomic mass unit(amu) or Dalton unit or grams/mol.Relative atomic mass is also the relative mass but does not have a unit but a ratio number.
AMU=Atomic Mass Unit
expressed in unified atomic mass unit, amuHowever, for practical purposes in the laboratory the relative atomic mass is used so the unit would be gram. (Relative atomic mass compares the mass of all elements to that of the carbon-12 isotope taken as exactly 12)
Scientists use atomic mass units (amu) or unified atomic mass units (u) to measure the mass of atoms and their subatomic particles. These units are based on the mass of a carbon-12 atom and are commonly used in the field of nuclear and particle physics.
Exactly the mass of an atom expressed in atomic units of mass (u).
Their mass is measured in atomic units 1 atomic unit is 1.660538782×10−27 kg A Proton has a mass of 1.007276466 u (u is the symbol for Atomic Mass) A Neutron has a mass of 1.008664915 u
The atomic mass of silver is approximately 107.87 atomic mass units.
The mass of protons and neutrons is typically measured in atomic mass units (u) or unified atomic mass unit (amu), which is defined as one twelfth of the mass of a carbon-12 atom.
The approximate mass of an oxygen atom in atomic mass units is 16. Oxygen has an atomic number of 8, which means that its atomic mass is approximately 16 atomic mass units.
