How to Find the Mass of One Atom of Helium (He)
There are two steps to find the mass of the Helium (He) atom. First we find the atomic mass of He from the Periodic Table. We then divide this by Avogadro's Number (6.02 x E23). Note that this is the mass of an average atom of Helium since the periodic table lists the average atomic mass for elements. If you were given a specific isotope of ...
