  2. Template:Atomic mass - Wikipedia

    en.wikipedia.org/wiki/Template:Atomic_mass

    The mass of an atom or a molecule is referred to as the atomic mass. The atomic mass is used to find the average mass of elements and molecules and to solve stoichiometry problems. The name "atomic mass" is used for historical reasons, and originates from the fact that chemistry was the first science to investigate the same physical objects on ...

    Atomic number Element Molar mass Formal standard atomic weight s.a.w., formal short Note Z calculated; g·mol −1 A r, standard [2] A r, abridged and conventional [2]; C 9 H 8 O 4: 180.159 g·mol −1

  4. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [2] or the conventional atomic weight.

  5. Atomic mass - Wikipedia

    en.wikipedia.org/wiki/Atomic_mass

    Alternately, the atomic mass of a carbon-12 atom may be expressed in any other mass units: for example, the atomic mass of a carbon-12 atom is 1.992 646 882 70 (62) × 10 −26 kg. As is the case for the related atomic mass when expressed in daltons , the relative isotopic mass numbers of nuclides other than carbon-12 are not whole numbers, but ...

    For example, in the study of Bose–Einstein condensate, [6] atomic mass m is usually given in daltons, instead of kilograms, and chemical potential μ is often given in the Boltzmann constant times nanokelvin. The condensate's healing length is given by: =.

  7. Nuclear density - Wikipedia

    en.wikipedia.org/wiki/Nuclear_density

    The mass density ρ is the product of the number density n by the particle's mass. The calculated mass density, using a nucleon mass of m n =1.67×10 −27 kg, is thus: ρ 0 t h e o r = m n n 0 t h e o r ≈ 2 × 10 17 k g m − 3 {\displaystyle \rho _{0}^{\mathrm {theor} }=m_{\mathrm {n} }\,n_{0}^{\mathrm {theor} }\approx 2\times 10^{17 ...

  8. Mass number - Wikipedia

    en.wikipedia.org/wiki/Mass_number

    The mass number (symbol A, from the German word: Atomgewicht, "atomic weight"), [1] also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It is approximately equal to the atomic (also known as isotopic) mass of the atom expressed in atomic mass units.
