How are the mole and atomic masses of elements related?  

• The atomic mass of any substance is always equal to 1 mole of that substance 

• The atomic mass added up with itself by 6.02 x 10²³ equals the amount of atoms

• The atomic mass is the amount of protons plus number of atoms

• Atoms combined make up molecules, which are the measurement of atomic masses
