Atomic weight is expressed using grams/mol or atomic mass units (u) while atomic mass is quantified using atomic mass units (u). Accurate values of atomic weights of all the elements are given in Table A.4 in A
atomic mass rounded off to an integer.1962Nature19 May 621/1Some confusion of meaning..could be avoided if ‘atomic mass’ were reserved for the species of matter now known as nuclides and ‘atomic weight’ were used only in its traditional connotation, that is, for elements.1963Jerrard & ...
Facilitated transport rates can reach ~1000 translocation events or a mass flow of 100 MDa per NPC per second6, and NPC passage of a single molecule is usually completed within milliseconds to tens of milliseconds7,8,9, even for ribosomal subunits10. In fact, passage through the NPC barrier...
of that atom. This unit is the basis for determining the relative atomic weight for all other elements. A hydrogen atom is assigned an atomic weight of 1 (rounded from 1.008) because the mass of a hydrogen atom is roughly equal to 1/12th the mass of a ...
A launch laser or mass driver powerful enough to boost huge masses into orbit can smash a combat starship like a sledge-hammer hitting a cockaroach. If there is a planetary disaster, spaceports will suddenly be thrust into the role of operational center. After all, it will be the source ...
Galactic a galaxy, most or all of its stars, up to all mass associated with it. Universal the entire universe, all or most galaxies within it, or all major galaxy filaments or equivalent highest-level structures. Multiversal multiple universes, or whatever that exists outside of the setting'...
A smaller tube ran from the engines forward, but you couldn't see all of it because big rounded reaction mass canisters covered part of it. Up forward the arms grew out of another cylinder. They jutted out at equal angles around the hull, three big arms to contain passenger decks and ...
In order to maximize the utility of concepts developed for lunar structural design, mass rather than weight-based criteria should be the approach of lunar structural engineers. All of NASA’s calculations have been done in kgforce rather than newtons. Calculations are always without the gravity ...
Themass of a He-3atom is 3.016 AMU (atomic mass unit, also sometimes denoted u), the mass of a deuteron is 2.014 AMU. One AMU is 1.66E-27 kg. This lets you find the mass of all the reactants going in to the fusion reaction. ...
