      n     (Chem)  
1    the mass of an isotope of an element in atomic mass units  
2    short for relative atomic mass; see atomic weight  
atomic mass unit  
      n   a unit of mass used to express atomic and molecular weights that is equal to one twelfth of the mass of an atom of carbon-12. It is equivalent to 1.66x10--27 kg,   (Abbrev.)    amu     (Also called)    unified atomic mass unit, dalton

critical mass  
      n   the minimum mass of fissionable material that can sustain a nuclear chain reaction  
gravitational mass  
      n   the mass of a body determined by its response to the force of gravity

High Mass  
      n   a solemn and elaborate sung Mass

Low Mass  
      n   a Mass that has a simplified ceremonial form and is spoken rather than sung  
   Compare       High Mass
