3. Na2SO4 4. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu". Also, important in this field is Avogadro's number (N A) or Avogadro's constant (6.0221 x 10 23). The term "mole" is defined in that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram.
