ormula weight指分子量 molecular weight指分子式 指分子式时用molecular weight 要是说分子量用ormula 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...
while the formula and molecular mass of glucose are different from each other. The formula mass (formula weight) of glucose is 30 (either no units or else grams per mole), while the molecular mass (molecular weight) is 180.156 g/mol. Whenever you see a molecular formula where you can div...

All you need to know to use our molecular weight (MW) calculator is the chemical formula of the particle you want to calculate. Choose the first element of your chemical formula. Enter how many of that atom it has. Repeat the process as many times as you need to complete your formula!
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
