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.
They are both are a measure of mass. 1 atomic mass unit = 1.66053886 Ã 10-27 kilograms = 1.66053886 Ã 10-24 grams. You can look this value up in books/online pages. You can derive it by realizing that 1 amu is defined as 1/12th the mass of a C-12 atom.
