Mole Relationships

 

1 mol molecules = 6.02 x 1023 molecules = molecular mass g = 22.4 L at STP = subscript mol atoms

IMPORTANT NOTE:  22.4 L can be replaced with 22,400 cc or 22,400 ml

ammonia =NH3

1 mol molecule = 6.02x1023 molecules = 17.0 g = 22.4 L = 4 mol atoms = 1 mol N atom = 3 mol H atom

     

1 molecule = molecular mass amu = subscript atoms

ammonia = NH3

 1 molecule ammonia = 17.0 amu = 4 atoms = 1 atom N = 3 atoms H

    

1 atom = atomic mass amu

nitrogen = N2

1 atom N = 14.07 amu

    

1 mol atoms = atomic mass g = 6.02 x 1023 atoms

nitrogen = N2

1 mol atoms N = 14.07 grams = 6.02 x 1023 atoms

     

1 L = 1000 cc = 1000 ml              1 cc = 1 ml

1 g = 6.02 x 10 23 amu

22.4 L = 22,400 ml = 22,400 cc
