I am a bit stuck on a basic chemistry concept. I understand that the Avogadro number indicates the number of chemical entities it has (ion, molecule or atom) What I don't understand is that when you add the masses of all of the elements in a compound, that it will equal to 6.022x10 atoms of that substance - why wouldn't there be more? For example shouldn't H2O have 3 X avogadros number (2X Hydrogen moles of 6.022x1023 and 1X mole of O).
Thanks!
