The atomic mass unit is defined as 1/12th the mass of a carbon-12 atom. This is not correct. The unified atomic mass unit u is defined as 1/12th the mass of a carbon-12 atom. The atomic mass unit (amu) is defined as 1/16th the mass of the oxigen-16 isotope (physics) or 1/16th of the (average) mass of an oxigen atom (chemists). Summary Carbon-12 is the reference for all atomic mass calculations. An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12. The mass of an atom is affected by the interactions of particles within the nucleus. 4.20 Calculating Average Atomic Mass Element Isotope (symbol) Percent natural abundance Atomic. Atomic Mass of Carbon. Atomic mass of Carbon is 12.0107 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams. The atomic mass unit is defined as 1/12th the mass of a carbon-12 atom. This is not correct. The unified atomic mass unit u is defined as 1/12th the mass of a carbon-12 atom. The atomic mass unit (amu) is defined as 1/16th the mass of the oxigen-16 isotope (physics) or 1/16th of the (average) mass of an oxigen atom (chemists).
