They showed that the helium nucleus is slightly less massive (by a mere percent) than the sum of the mass of the four hydrogen nuclei, or four protons. You can obtain the molar mass of any chemical element by using the periodic table: The molar mass is usually listed underneath the chemical symbol. The units.
