Have you ever wondered?






                                     3. What is the difference between


                                            atomic weight and atomic mass?







                                             Atomic mass is the mass of an atom.


                                             A single atom has a set number of


                                             protons and neutrons, so the mass is



                                             unequivocal  and is the sum of the


                                             number of protons and neutrons in


                                             the atom.
