  2. Dalton (unit) - Wikipedia

    en.wikipedia.org/wiki/Dalton_(unit)

    As a consequence, the molar mass constant remains close to but no longer exactly 1 g/mol, meaning that the mass in grams of one mole of any substance remains nearly but no longer exactly numerically equal to its average molecular mass in daltons, [30] although the relative standard uncertainty of 4.5 × 10 −10 at the time of the redefinition ...

  3. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    The dalton, symbol Da, is also sometimes used as a unit of molar mass, especially in biochemistry, with the definition 1 Da = 1 g/mol, despite the fact that it is strictly a unit of mass (1 Da = 1 u = 1.660 539 068 92 (52) × 10 −27 kg, as of 2022 CODATA recommended values).

  4. Molecular mass - Wikipedia

    en.wikipedia.org/wiki/Molecular_mass

    For example, water has a molar mass of 18.0153(3) g/mol, but individual water molecules have molecular masses which range between 18.010 564 6863(15) Da (1 H 2 16 O) and 22.027 7364(9) Da (2 H 2 18 O). Atomic and molecular masses are usually reported in daltons, which is defined in terms of the mass of the isotope 12 C (carbon-12).

  5. Molar mass constant - Wikipedia

    en.wikipedia.org/wiki/Molar_mass_constant

    The mole and the atomic mass unit (dalton) were originally defined in the International System of Units (SI) in such a way that the constant was exactly 1 g/mol, which made the numerical value of the molar mass of a substance, in grams per mole, equal to the average mass of its constituent particles (atoms, molecules, or formula units) relative ...

  7. Atomic mass - Wikipedia

    en.wikipedia.org/wiki/Atomic_mass

    One dalton is equal to 1 ⁄ 12 the mass of a carbon-12 atom in its natural state. Thus, the numeric value of the atomic mass when expressed in daltons has nearly the same value as the mass number . The value of 1 unified atomic mass unit in kilograms is m u = 1.660539066 × 10 − 27 k g {\displaystyle m_{\rm {u}}=1.660539066\times 10^{-27 ...
