Solution: 12/6.022*10^23 = 1.9927*10^-23. We know that carbon 12 has a mass of 12 a.m.u and 1 amu =1.66*10^-24 grams.
(1.9927x10^-23 g/atom) / (12 amu/atom) = 1.66x10^-24 g/amu. Disclaimer: I didn't check the actual calculations, so I apologize if the numbers are incorrect. This only applies to C-12 because it is used to define the atomic mass scale; in other isotopes, binding energies will affect the results.
