A Carbon Twelth
No, the SI unit of mass is still the kilogram. However, the AMU has been accepted as a suitable standard unit.
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.
because they are the sameAdded:Atomic mass is the quantitive propertie of the mass of an atom,the atomic mass unit is the (standard) UNIT by which it is measured:1 a.m.u. = 1.66*10-27 kg
The atomic mass unit (u) or unified atomic mass unit (amu) is the standard unit used to measure the masses of atomic particles such as protons, neutrons, and electrons. 1 atomic mass unit is defined as 1/12th of the mass of a single carbon-12 atom.
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
The unit used to measure weighted average atomic mass is atomic mass unit (amu). This unit is a standard for atomic and molecular mass measurements in chemistry and is defined as one twelfth of the mass of an atom of carbon-12.
The unit of atomic mass for aluminum is atomic mass unit (amu) or unified atomic mass unit (u).
One twelfth (1/12) the mass of a carbon-12 atom is one atomic mass unit (amu, or just u).
Atomic mass unit
The standard a.m.u. is 1/12th of the mass of a Carbon 12 nuclide.
The atomic mass unit is used to express the measure of the atomic mass.
