The atomic mass number of copper is A = 64. Assume that atoms in solid copper form a cubic crystal lattice. To envision this, imagine that you place atoms at the centers of tiny sugar cubes, then stack the little sugar cubes to form a big cube. If you dissolve the sugar, the atoms left behind are in a cubic crystal lattice.

2. Relevant equations

?

3. The attempt at a solution

This question is coming from the chapter dealing with Ideal-Gas laws. Also talks about moles and atomic mass numbers/atomic numbers, but I don't see how I can use the Ideal-gas laws (Boltzmann's constant) with a copper atom. I also don't see how knowing the atomic mass number even plays a roll in solving this problem... any help? I would honestly attempt the solution if I knew where to even start.
