Total number of fundamental particles in one mole of water is equal to ( NA = Avogadro's number )

Each oxygen atom, O816 contains….8 protons, 8 electrons and 8 neutrons ;Each hydrogen atom, H11 contains….1 proton, 1 electron and zero neutrons ;Thus each molecule of H2O contains…10 protons, 10 electrons and 8 neutrons ;Thus each mole (16 g) of H2O  contains…10 moles (10 NA) of protons, 10 moles (10 NA)  of electrons and 8 moles (8 NA)  of neutrons ;
