The weight of a substance that will combine with or replace one mole of hydrogen or one-half mole of oxygen. The equivalent weight is equal to the atomic weight divided by the valence. American Heritage® Dictionary of the English Language, Fifth Edition. Copyright © 2016 by Houghton Miff...
indicating that there are two atoms of hydrogen and one atom of oxygen in a molecule of water. Rounded to three decimal places, the atomic weight of hydrogen is 1.008 amu and that of oxygen is 15.999 amu. The molecular weight of water is thus (2×1.008)+(1×15.999)=2.016+15.999=18.015...
The sum of the atomic weights of the atoms contained in a molecule. For example, since the atomic weight of hydrogen is 1 and the atomic weight of oxygen is 16, the molecular weight of water (H2O) is 1 + 1 + 16, or 18.
I was looking up the atomic weight of Cobalt from 2 different resources. I noticed that there was a slight disparity between wikipedia.org and webqc.org. I then looked up the values for Oxygen, Carbon, and Hydrogen. http://www.webqc.org/periodictable-Cobalt-Co.html ...

9.1.1Air As stated previously, most combustion takes place between ahydrocarbon fueland air. Air is a mixture of gases, the most abundant being oxygen and nitrogen with small proportions of other gases. In fact, in practice air is a mixture of all elements and compounds because everything wi...
In capillary electrophoresis, the sensitivity of amine detection of the laser-induced fluorescence is in the subattomole range (<10-18 moles) for ATTO-TAG CBQCA and subfemtomole range (<10-15 moles) for ATTO-TAG FQ. Detectio...
