An easy way to get through Stoichiometric calculations in chemistry is to use Dimensional Analysis in conjunction with a table of units like this one (in glorious ASCII):

          L of A -------------------------------------- L of B            
            ||                   -1-                      ||              
            ||                                            ||              
            || -2-                                        || -3-          
            ||                                            ||              
  g of A -------------------------------------------------------- g of B  
    -4-     ||                   -1-                      ||      -5-     
            ||                                            ||              
            ||                                            ||              
            ||                                            ||              
      Particles of A ------------------------------- Particles of B       
            -6-                  -1-                       -7-

Where '\' is a fraction bar:

-1- coefficient of B \ coefficient of A

-2- 22.4 L \ 1 mol

-3- 1 mol \ 22.4 L

-4- molecular mass (g) \ 1

-5- 1 \ molecular mass (g)

-6- 6.02x10^23 Particles \ 1 mol

-7- 1 mol \ 6.02x10^23 Particles

NOTE: -2- and -3- are only applicable to gasses at STP

When you master Stoichiometric calculations, everyone in your Chemistry class will think you shit diamonds from a platinum asshole. You may also become quite popular. Xerox your homework and sell it. It worked for me.
