1 atomic mass unit is eqal to the mass of one-twelth of mass of one atom of carbon atom. one atomic mass unit is exactly equal to one-twelfth the mass of carbon isotope-12. it is taken with reference to atomic mass of one twelfth of carbon isotope 12. One amu (or dalton) is exactly one twelfth of the mass of an atom of the most common form of carbon. 1 amu = 1.0078...
The mass number gives an estimate of the isotopic mass measured in atomic mass units (u). For 12 C the isotopic mass is exactly 12, since the atomic mass unit is defined as 1/12 of the mass of 12 C. For other isotopes, the isotopic mass is usually within 0.1 u of the mass number. For example, 35 Cl has a mass number of 35 and an isotopic mass of 34.96885.
