Molecular weight and atomic weight Atomic weight is useful for determining a substance’s molecular weight—the average combined weight of a molecule’s individual atoms. Like atomic weight, molecular weight is an averaged weight, based on the relative abundance of each atom’s isotopes. Let’s ...
Related to atomic weight:molecular weight atomic weight n. The average mass of an atom of an element, usually expressed relative to the mass of carbon 12, which is assigned 12 atomic mass units. American Heritage® Dictionary of the English Language, Fifth Edition. Copyright © 2016 by Hou...
The atomic weight of an atom, or the molecular weight of a molecule, is its mass relative to that of a(n) ___ atom. This is essentially equal to the number of protons plus neutrons that the atom or molecule contains.的答案是什么.用刷刷题APP,拍照搜索
then the atomic mass and the atomic weight will be the same. Atomic mass and atomic weight may equal each other whenever you are working with a single isotope of an element, too. In this case, you use the atomic mass in calculations rather than the atomic weight of the element from the...
