To find the molecular weight, add the weights of all the atoms in the molecule. A simple formula to follow is: Molecular weight = thesumof (# of molecules of each elementtimesthe atomic weight of that element) for each element What is the meaning of molecular weight?
我只见过molecular weight，指的是相对分子质量，比如HCl约等于36.5，是要计算自然界同位素丰度比的，35Cl,37Cl在自然界的存在比约为3:1 formula weight没大见过，有一种叫“Exact mass”的指的是分子中所有的原子按最小质量的同位素计算，比如HCl约等于36.0，也就是Cl用35计算。我想或许你这里的for...
molecular weight指分子式 指分子式时用molecular weight 要是说分子量用ormula weight Formula weight=Molecular weight （如果该化合物是free base）；Formula weight=Molecular weight + HCl (如果该化合物是盐酸盐)。
