The term "salt" can refer to any of a number of ionic compounds, but it is most commonly used in reference totable salt, which is sodium chloride. The chemical or molecular formula for sodium chloride is NaCl. The individual units of the compound stack to form a cubic crystal structure. ...
Table salt isan ionic compound, which breaks into its component ions ordissociatesin water. These ions are Na+and Cl-. The sodium and chlorine atoms are present in equal amounts (1:1 ratio), arranged to form a cubic crystal lattice. The molecular formula of table salt—sodium chloride—is...

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together....
是指一个 formula unit 的 particle 的 relative mass。本来是该用于没有 molecule 的 particle 的 relative mass。例如 NaCl 含 ions 而不含 molecules，所以没有 r.m.m.，但 NaCl 含一个 Na+ ion 和一个 Cl- ion，所以 f.m. of NaCl = 23 + 35.5 = 58.5。但 f.m. 可应用于任何...
1请大家帮忙翻译一段话(和核磁共振有关),万分感谢呀Compound 7 was assigned the molecular formula C30H48O3 by HRESIMS. Analysis of the 1H and 13C NMR spectra (Table 2) indicated 7 and 6 had the same lanostane skeleton, but a different side chain. The NMR data for the side chain part,re...
of the things that gives caffeine its addictive qualities. Molecular Formulas The final step in identifying an unknown compound is determining the molecular formula, which shows the actual number of atoms in each molecule of the substance. To determine the molecular formula, the molar mass of the...
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula ...
