100 atoms is the same as how many moles?
nº atoms /avogadre number= nº of moles
100/6,022x10^23= 1,66x10^-22 moles
the molar mass is: mass/moles
we know that the molar mass of carbon 12 it's the same as his atomic number, which is 12.
So, using the previous formula:
12= mass/ 1,66x10^-22
mass= 1,992x10-21 grams of carbon 12
Yes they did in many different ways
