Aluminum has a density of 2.699 g/cm3 , and the atoms are packed in a face-centered cubic crystal lattice. Find the mass of a unit cell.
-----I already know the answer is 1.792*10^-22g/unit cell
I have a question about how you get the answer:
I know you multiply 4.480*10^-23g * 4 atoms/1 unit cell= the answer
where does the 4 atoms come from???
