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.
One number is carbon's element number or atomic number. Atomic number increase as you go across the table. This is not the value you want. The atomic mass or atomic weight is the decimal number, The number of significant figures varies according to the table, but the value is around 12.01. This value on a periodic table is given in atomic mass units or amu, but for chemistry calculations, you usually write atomic mass in terms of grams per mole or g/mol.
