my teacher was like everything on the periodic table is one mole
I know that 1mol=6.02x10^23 atoms/molecules/whatever
but why is everything on the periodic table 1 mole. and why is it compared carbon-12
the thing im really confused me is: if 1 ATOM of an element is 1 mole, does it mean that there are 6.03x10^23 something making up that 1 ATOM of that element.
I also know some atoms are made up isotopes, but some are made of 1 isotope
