Answer:
Atomic mass unit is defined as a mass exactly equal to 
the mass of carbon-12 atom (6C12).
the mass of carbon-12 atom (6C12).1 a.m.u. = the mass of Carbon-12.
the mass of Carbon-12.As 1 mole of C = 6.022 Χ 1023 atoms and atomic mass of carbon = 12 grams = 1 mole.
So, 6.022 Χ 1023 atoms of carbon weighs = 12 grams of C
