the answer is the atomic mass unit
12u (unified atomic mass unit)
or
12g/mol
Atomic Mass Unit (amu)
1 amu (atomic mass unit), by definition.
none
12 amu
One-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
a unit of mass used to express atomic and molecular weights, equal to one-twelfth of the mass of an atom of carbon-12. It is equal to approximately 1.66 x 10^-27 kg.
Unified atomic mass unit, a small unit of mass used to express atomic and molecular masses. The atomic mass unit is equal to one-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
Atomic Mass is the mass of an atom of a chemical element expressed in atomic mass units. It 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.Relative atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12.Relative isotopic mass is the mass of an atom of an isotope of an element compared with one-twelfth the mass of an atom of carbon-12.Thus an element will have ONE Relative Atomic Mass but there may be MANY individual Relative Isotopic Masses for an Element (depending on how many Isotopes it has).
Aunified atomic mass unit is equal to one-twelth the mass of a carbon-12 atom.
One atomic mass unit (amu)
Atomic mass.
i think it is atomic mass unit
The average atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. It is, the mass of an atom of the substance, rescaled so that carbon-12 would have a mass of 12.
One-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
The atomic mass unit uses carbon-12 as a standard. The atomic mass unit is one twelfth of the mass of one atom of the isotope carbon-12.
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.
