2.   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 10 23  6.02 x 10 23 is also know as Avagadro’s number after the scientist  Why would scientists use such a large number? What is a mole?

3.   Avagadro’s number is used to convert between moles and particles.  1 mole = 6.02 x 10 23 particles  Particles can be atoms, ions, or molecules Avagadro’s Number

4.   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

5.   Convert 8.23 moles of NaCl to molecules Example

6.   2.98 x 10 25 atoms of Silver are equal to how many moles of Silver? Example

7.   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

8.   23 moles of chlorine gas has a volume of how many liters? Example

9.   98 Liters of Hydrogen gas is exactly how many moles? Example
