I believe it is the last answer, hope this helps!
<span>greater dispersion forces is in fact correct</span>
The molar mass of copper is 63.55 g/mol. So, you convert grams to moles 127.08/63.55 =1.999 moles copper. Now, 1 mole = 6.022e23 atoms, so multiply # of moles by 6.022e23. 1.999 x 6.022e23= # of atoms of copper.
It could be a couple different thing, explain more.<span />
