The meaning of MOLECULAR WEIGHT is the average mass of a molecule of a compound compared to 1/12 the mass of carbon 12 and calculated as the sum of the atomic weights of the constituent atoms.
Molecular weight, mass of a molecule of a substance, based on 12 as the atomic weight of carbon-12. It is calculated in practice by summing the atomic weights of the atoms making up the substance’s molecular formula. The molecular weight of a hydrogen m
MW — molecular weight; C— atomic mass of carbon; H— atomic mass of hydrogen; and O— atomic mass of oxygen. Find your elements in the periodic table of the elements. The atomic mass is usually shown below the symbol of the element. C— 12 u; H— 1 u; and O— 16 u. Input ...

Themolecular massof a substance is the mass of one molecule of that substance, in unifiedatomic mass units(Drews, 1998; Speight, 2015). This is distinct from therelative molecular massof a molecule, frequently referred to by the termmolecular weight, which is the ratio of the mass of that...
The atomic weight of an atom, or the molecular weight of a molecule, is its mass relative to that ofa___ atom. This is essentially equal to the number of protons plus neutrons that the atom or molecule contains. A oxygen B hydrogen C helium D carbon 相关知识点: 试题来源: 解析 B ...
