WebJun 26, 2024 · The atomic weight is calculated by adding the mass of each isotope multiplied by its fractional abundance. For example, for an element with 2 isotopes: atomic weight = mass a x fract a + mass b x fract b If there were three isotopes, you would add a 'c' entry. If there were four isotopes, you'd add a 'd', etc. Atomic Weight Calculation Example WebA mole tells you the amount of something, in units of Avogadro's number. It doesn't matter how big or small the molecule is, just how many of them there are. Here, it takes 1 mole of K and 1 mole of Cl to make 1 mole of KCl because KCl is a bigger molecule than K or Cl and one molecule needs exactly 1 K and 1 Cl atom.
