## Homework Statement

Estimate the diameter of an atom of a substance whose density is 10

^{3}kg/m

^{3}

## Homework Equations

V

_{atom}= 4 [tex]\pi[/tex] r

^{3}/3

[tex]\sigma[/tex] = m/V

## The Attempt at a Solution

I have attempted a few different things, but I always come out a variable short, and although they question says estimate, I can't see that I can estimate a variable like atomic weight as it varies too much for an estimate to be reasonable.

I have rearranged equations to get:

V = m/[tex]\sigma[/tex] = n [tex]\times[/tex] N

_{A}[tex]\times[/tex] (4/3) [tex]\times[/tex] [tex]\pi[/tex] [tex]\times[/tex] r

^{3}

I don't even know how close together the atoms are as I don't know the sate of the substance.
