The best answer to this question is not 39 amu, but it's how to read the periodic table. A very simple one looks like: Underneath each element is the mass of each element in amu (or atomic mass units). Each amu is equal to 1.67 x 10^-27 kg. read more
Underneath each element is the mass of each element in amu (or atomic mass units). Each amu is equal to 1.67 x 10^-27 kg. There is a wealth of physics and chemistry contained in this table, but starting with the foundations is the best place to start! read more
