* Atomic Mass Units (amu): An atomic mass unit (amu) represents the mass of a single atom of a specific element. Carbon's atomic mass of 12 amu means a single carbon atom weighs 12 amu.

* Moles: A mole is a unit of measurement for the amount of substance. It's defined as the number of atoms or molecules contained in 12 grams of carbon-12. This number is known as Avogadro's number (6.022 x 10^23).

Therefore, 1 mole of pure carbon will have:

* 12 grams of carbon. This is because the atomic mass of carbon (12 amu) is numerically equal to the molar mass of carbon in grams per mole (12 g/mol).

* 6.022 x 10^23 carbon atoms. This is Avogadro's number, the number of atoms in one mole of any substance.
