Harder Mole Conversion

At the previous class of the mole conversion, we've learnt:
-From particles → moles.
-From moles → particles/molecules/formula units/atoms
-From moles → grams
-From grams → moles

The previous sections showed how to perform single-step conversions between moles and any of mass, volume, or number of particles.  This section shows how to convert between mass and volume, number of particles and mass, and so on.  The box table below summarizes the conversion factors needed.


                            Conversion                    |              Conversion Factor       
          
                                                                        6.022x10^23 particles
                 -mole → particles                     |               1 mole
                ______________________________________________________       
               
                  -mole → mass                        |      molar mass g                                  
                                                                             1mol
                ______________________________________________________

                -mole → volume                       |           22.4 L
                                                                           1 mol
                ______________________________________________________

               -molecules → atoms                |           # atoms      
                                                                         1 molecule
