The mole[1] is defined as the number of particles in #12 "g"# of carbon-#12#, known as #""12C#. So, we say that in one mole of carbon-#12#, the sample has a mass of #12 "g"#.
In other words,
#"mass of carbon-12"=12 "g/mol"#.
Still with me? Good.
Now, we also know that the mass of a single carbon-#12# atom is exactly #12 "amu"#, as it is an isotope.
And so,
#"mass of carbon-12"=12 "amu/atom"#
Combining, we have:
#12 "amu/atom"=12 "g/mol"#
#=>1 "amu/atom"=1 "g/mol"#
Therefore we just proved that an atomic mass[2] unit is the same thing as grams per mole. Hope this helps!
