atomic mass definition
1 atomic mass unit is defined as 1/12 of the mass of a single carbon-12 atom. :18 1 u has a value of 1.660 539 066 60(50) × 10−27 kg. ,The atomic mass (ma or m) is the mass of an atom. Although the SI unit of mass is kilogram (symbol: kg), the atomic mass is often expressed in the non-SI unit dalton (symbol: Da, or u) where 1 dalton is defined as 1⁄12 of the mass of a single carbon-12 a
