Definition of atomic mass unit in English English dictionary: a unit of mass equal to 1/12 the mass of an atom of the 12C isotope of carbon; Unit of mass defined by the convention that the atom 12C has a mass of exactly 12 u; the mass of 1 u is 1 67 ´ 10-27 kg; Atomic Mass Unit (u): This is a convenient mass unit to use when dealing with the masses of atoms and nuclear particles Were the mass expressed in kilograms the values would be so tiny they would be difficult for students to deal with The unit is defined by taking the mass of one atom of carbon12 as being 12u This makes the mass of a proton and a neutron to be equal to 1u (when measured to the degree of accuracy needed for GCSE level) 1u = 1 661 x 10-27 kg 1kg = 6 020 x 1026 u (Note - Some text books use the abbreviation amu); A unit of mass equal to the mass of the most abundant isotope of carbon, carbon 12, which is assigned a mass of; {i} unit of mass equal to 1/12 the mass of a carbon atom, AMU; Also called dalton; mass unit equal to exactly one-twelfth the mass of carbon-12 ie 1 amu = 1 66056 x 10-24 g eg C-12 has a relative atomic mass of 12 (i e 12 amu); A unit of mass equal to 1/16-th the mass of the atom of oxygen of atomic mass number 16, meaning that there are 16 nucleons in the standard oxygen nucleus A nucleon is either a proton or a neutron In terms of energy (using E = mc^2) an AMU = 931 Mev = 1 49 X 10^(-3) ergs; One-twelfth of the mass of carbon-12, or 1 6605655 x 10-27 kg; a unit of mass equal to 1/12 the mass of the carbon isotope with mass number 12, approximately 1 6604 x 10E-24 gram; A unit of mass equal to 1/12 the mass of an atom of the carbon isotope with mass number 12; approximately 1 66 x 10-27 kilogram; unit of mass for expressing masses of atoms or molecules; one twelfth of the arbitrary mass assigned to carbon 12 It is equal 1 6604 x 10 24 gm; Chemical: one-sixteenth of the mean mass of an oxygen atom Physical: one-twelfth of the mass of an atom of the most common isotope of carbon The atomic mass unit is approximately the mass of a hydrogen atom, 1 67 x 10^-27 kg; One-twelfth of the mass of a carbon-12 atom It is approximately equal to the mass of a single proton or neutron; the weight of one proton or neutron; Standard unit that corresponds to one twelfth of the mass of the carbon isotope 12C6 (= 1 6604 x 10-24 g); amu
