Some articles on mass, atomic, atomic mass:
Whole Number Rule
... that the masses of the isotopes are whole number multiples of the mass of the hydrogen atom ... a modified version of Prout's hypothesis proposed in 1815, to the effect that atomic weights are multiples of the weight of the hydrogen atom ... Aston demonstrated through the use of a mass spectrometer that apparent deviations from Prout's hypothesis are predominantly due to the existence of isotopes they are ...

Planck Constant - Dependent Physical Constants - Avogadro Constant
... The Avogadro constant NA is determined as the ratio of the mass of one mole of electrons to the mass of a single electron The mass of one mole of electrons is the "relative atomic mass" of an electron Ar(e), which ... It is possible to measure the masses more precisely in atomic mass units, but not to convert them more precisely into kilograms ...

Mass Number - Atomic Mass of An Element
... The mass number should also not be confused with the relative atomic mass (also called atomic weight) of an element, which is the ratio of the average atomic mass of ... In any given sample of chlorine that has not been subject to mass separation there will be roughly 75% of chlorine atoms which are chlorine-35 and only 25% of chlorine atoms which are ... This gives chlorine a relative atomic mass of 35.5 (actually 35.4527 g/mol) ...

Prout's Hypothesis - Influence
... However, more careful measurements of the atomic weights, such as those compiled by Jöns Jakob Berzelius in 1828 or Edward Turner in 1832, disproved the hypothesis ... In particular the atomic weight of chlorine, which is 35.45 times that of hydrogen, could not at the time be explained in terms of Prout's hypothesis ... Although they turned out to be wrong, these conjectures catalyzed further measurement of atomic weights, a great benefit to chemistry ...

Nuclear Reaction - Energy Conservation
... as follows according to the reference tables, the 6 3Li nucleus has a relative atomic mass of 6.015 atomic mass units (abbreviated u), the deuterium has 2.014 u, and the helium-4 nucleus has 4.0026 ... The "missing" rest mass must therefore reappear as kinetic energy released in the reaction its source is the nuclear binding energy ... Using Einstein's mass-energy equivalence formula E = mc², the amount of energy released can be determined ...

Famous quotes containing the words mass and/or atomic:
“A serious problem in America is the gap between academe and the mass media, which is our culture. Professors of humanities, with all their leftist fantasies, have little direct knowledge of American life and no impact whatever on public policy.”
—Camille Paglia (b. 1947)
“No atomic physicist has to worry, people will always want to kill other people on a mass scale. Sure, he’s got the fridge full of sausages and spring water.”
—William Burroughs (b. 1914)
