  2. 2. Ju s t like a dozen re p re s e nts 1 2 of s om e th ing,s u ch as d onu ts , igu anas , ch e m is try as s ignm e nts , e tc., a mole als o re p re s e nts an am ou nt of s om e th ing. It is 6.02 x 1 0 23 of s om e th ing. A m ole can re p re s e nt 6.02 x 1 0 d onu ts , igu anas , toe s , e tc. 23 In ch e m is try, it is norm ally u s e d to re p re s e nt an am ou nt of atom s , ions , m ole cu le s , or form u la u nits . C olle ctive ly, atom s , ions , m ole cu le s , or form u la u nits are calle d re p re se ntative p articl s . e
  3. 3. Because chemists deal with suchlarge amounts of particles,it is easier to work with moles of particles
  4. 4. amounts of particles can be expressednot only as moles,but as mass (grams),as volume (liters), andas individual particles (atoms, molecules, ions, formula units, etc.)
  5. 5. a measurement of a sampleof a molecule, H2O for example,can be converted O Hfrom mass Hto molesto particlesto volumeand back againto any unit of measurement desired
  6. 6. usingthe right this is soconversion cool!!factors
