Question

jfraser · Answer

You need to know what the formula of that "stuff" is, so we can determine how many atoms make up a single unit of that formula.  We also need the link between ## of atoms and mass.

anonymous · Answer

the answer in the bok says 3.56 x 10^24 total atoms and 2.96 x 10^24 atoms F

anonymous · Answer

molecular weight contains avogadro number of molecules. so 125 gains ... number of molecules. then multiplies by atomicity to get individual atoms
