What is the difference between atomic mass and relative atomic mass?
Verified Answer
What is the difference between atomic mass and relative atomic mass?
The unified atomic mass unit (symbol: u) or dalton (symbol: Da) is the standard unit that is used for indicating mass on an atomic or molecular scale (atomic mass). One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol.
Atomic mass the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Relative atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12.
Atomic mass is just the mass of atoms in an element BUT they are not necessarily the same mass so we get Chlorine as 35.453 u ! 0.002 u!
This is because different isotopes of an element will have different weights and in nature many elements come as mixtures of a number of isotopes.
