You can't solve the first portion because you'r emissing a variable. Density = mass over volume. If you only have the density, then you need one more variable in order to ascertain the weight of an iron atom. Now, once you solved that, you're also missing another variable in the second equations. I think you might be talking about avogadro's number and mole conversion?
They are vague and unsolvable at this point.
