  The difference in the mass of 100 moles each of sodium atoms and sodium ions is 5.48002 g. Compute the mass of an electron.   

Answer:

                  A sodium atom and ion differ by one electron. For 100 moles each of sodium atoms and ions there would be a difference of 100 moles of electrons. Mass of 100 moles of electrons = 5.48002 g Mass of 1 mole of electron Mass of one electron
