well for this you have to know the number of bb's in a mole (avogadro's number  ;) ) and the surface area of New Jersey

go from there

The world is like an atom. The not-quite-as-intelligent people are the nucleus all packed together sharing a common...everything. We, we are the electrons. Granted we're not as smart as these engineers and what-not so we're most likely in the first orbital, but we're the electrons of this giant atom. We all have differing intelligences and ideas and we are separated from the nucleus which makes us better because no one really cares about how a nucleus acts. It's the electrons that make chemistry, except for nuclear chem, of course, which I am a big fan of.

6.02*10^23 parts per mole. then find the area of NJ and the area that each bb takes up and go from there.

The area of NJ is :

7,836 sq miles / 20 295 sq kil

Can the BB be battleship (not chemistry but you can have its mole)!
