HARDER Mole Conversions



(click to enlarge)



Conversions between: PARTICLES → MASS

E.g. WHAT IS THE MASS OF:  1.34x10²² Zn atoms?   

           

     1.34x10²² atoms  X  .  1 mole      . X      65.4g  .  =   1.46g  of Zn

                                                 6.022x10²³          1 mole

Conversions between: GRAMS → PARTICLES

E.g.  HOW MANY ATOMS WOUD YOU HAVE IF YOU HAVE 10.0g OF COBALT?

            10.0g   X     1 mole  .  X   6.022x10²³   =   1.02x10²³  atoms of  Co

                                      58.9g               1 mole
