Atomic weight definitions start at greater than sodium (22.98) to greater than 40.
This procedure enabled chemists to determine the new element's atomic weight.
Copper has a density of 8.94 g/cm, and an atomic weight of 63.546 g/mol, so there are mol/m.
Equivalent weight has the dimensions and units of mass, unlike atomic weight, which is dimensionless.
It is numerically equal to the relative atomic mass (or atomic weight) in grams.
By contrast, there is less variation in naturally occurring hydrogen so the average atomic weight is known more precisely.
Her research focus was on aromatic acids and the atomic weight of palladium.
However, atomic weight, ie, relative atomic mass, is a dimensionless quantity, and can not take the units of grams per mole.
However, as noted in the introduction, atomic weight and standard atomic weight represent terms for averages of isotopic abundances, not for single nuclides.
Work on organizing the elements by atomic weight had hitherto been stymied by inaccurate measurements of the atomic weights.
Hydrogen-1, the lightest isotope of hydrogen and the atom with the lowest mass, has an atomic weight of 1.007825 u.

These radicals have low atomic weights while the persulfate molecule has a high atomic weight (238).
It could be added that atomic weight is often not truly atomic either, as it does not correspond to the property of any individual atom.
