  A mole is a counting unit similar to a dozen. A dozen is associated with the number 12 while a mole is associated with the number 6.02 x  6.02 x is also know as Avagadro’s number after the scientist  Why would scientists use such a large number? What is a mole?

  Avagadro’s number is used to convert between moles and particles.  1 mole = 6.02 x particles  Particles can be atoms, ions, or molecules Avagadro’s Number

  Just like using molar mass to convert back and forth between moles and grams we can use Avagadro’s number as a conversion unit to convert between moles and particles.  When going from moles to particles use:  When going from particles to moles use: Conversion Units

  Convert 8.23 moles of NaCl to molecules Example

  2.98 x atoms of Silver are equal to how many moles of Silver? Example

  Another mole conversion unit that can be used in chemistry is 1 mole=22.4 Liters of a gas  This can be used to go back and forth between moles and liters of a gas  When going from moles to liters use:  When going from liters to moles use: Conversion Unit

  23 moles of chlorine gas has a volume of how many liters? Example

  98 Liters of Hydrogen gas is exactly how many moles? Example
