The ideas of relative atomic mass and relative formula mass help us link these pictures to real masses of real objects. The relative atomic mass, or Ar, describes the mass of an element. it's the mass number you can look up in the periodic table. The mass number is the larger of the two numbers- so the mass number of aluminium is 27.
