For average weighted atomic mass shown in the Periodic table, prove the numerical value of Na is the same with either unit of AMU (atomic mass unit) or grams/mole. You must show your calculations in detail with units written for each step.
1 AMU = 1.66054e-24 grams
By definition, 12.0000 AMU equals the mass of 1 Carbon-12 atom (isotope).
The standard scientific unit used to quantify the amount of a substance in macroscopic quantities is the mole (symbol: mol), which is defined arbitrarily by the scientific community as the amount of a substance which has as many atoms or molecules as there are atoms in 12 grams of the carbon isotope C-12. The number of atoms in a mole is called Avogadro’s number, the value of which is approximately 6.022140857(74)×1023 mol−1.
