  2. Levée en masse - Wikipedia

    en.wikipedia.org/wiki/Levée_en_masse

    Levée en masse (French pronunciation: [ləve ɑ̃ mɑs] or, in English, mass levy [1]) is a French term used for a policy of mass national conscription, often in the face of invasion. The concept originated during the French Revolutionary Wars, particularly for the period following 16 August 1793, [2] when able-bodied men aged 18 to 25 were ...

  3. Mass versus weight - Wikipedia

    en.wikipedia.org/wiki/Mass_versus_weight

    L. Use of the Terms "Mass" and "Weight" [See Section K. NOTE] When used in this handbook, the term "weight" means "mass". The term "weight" appears when inch-pound units are cited, or when both inch-pound and SI units are included in a requirement. The terms "mass" or "masses" are used when only SI units are cited in a requirement.

  4. Mass - Wikipedia

    en.wikipedia.org/wiki/Mass

    If a first body of mass m A is placed at a distance r (center of mass to center of mass) from a second body of mass m B, each body is subject to an attractive force F g = Gm A m B /r 2, where G = 6.67 × 10 −11 N⋅kg −2 ⋅m 2 is the "universal gravitational constant". This is sometimes referred to as gravitational mass.

  5. Maß - Wikipedia

    en.wikipedia.org/wiki/Maß

    An empty Maßkrug. Maß (pronounced ) or Mass (Swiss spelling, elsewhere used for dialectal ) is the German word describing the amount of beer in a regulation mug, in modern times exactly 1 liter (33.8 U.S. fl oz; 1.8 imp pt).

  6. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    The molecular mass (for molecular compounds) and formula mass (for non-molecular compounds, such as ionic salts) are commonly used as synonyms of molar mass, differing only in units (daltons vs g/mol); however, the most authoritative sources define it differently. The difference is that molecular mass is the mass of one specific particle or ...

  7. Mass (mass spectrometry) - Wikipedia

    en.wikipedia.org/wiki/Mass_(mass_spectrometry)

    The monoisotopic mass is the sum of the masses of the atoms in a molecule using the unbound, ground-state, rest mass of the principal (most abundant) isotope for each element. [12] [5] The monoisotopic mass of a molecule or ion is the exact mass obtained using the principal isotopes. Monoisotopic mass is typically expressed in daltons.

  8. Monoisotopic mass - Wikipedia

    en.wikipedia.org/wiki/Monoisotopic_mass

    Nominal mass is a term used in high level mass spectrometric discussions, it can be calculated using the mass number of the most abundant isotope of each atom, without regard for the mass defect. For example, when calculating the nominal mass of a molecule of nitrogen (N 2) and ethylene (C 2 H 4) it comes out as. N 2 (2*14)= 28 Da C 2 H 4

  9. Effective mass (solid-state physics) - Wikipedia

    en.wikipedia.org/wiki/Effective_mass_(solid...

    The name "density of states effective mass" is used since the above expression for N C is derived via the density of states for a parabolic band. In practice, the effective mass extracted in this way is not quite constant in temperature (N C does not exactly vary as T 3/2). In silicon, for example, this effective mass varies by a few percent ...
