Final answer:
To determine the number of atoms in 8.68 mol of copper, multiply the number of moles by Avogadro's number (6.02 x 10^23 atoms/mol). Therefore, there are approximately 5.23 x 10^24 atoms.
Step-by-step explanation:
To determine the number of atoms in 8.68 mol of copper, we first need to find the number of moles in 1 copper atom. The atomic mass of copper is 63.54 g/mol, so 1 mole of copper contains 6.02 x 10^23 atoms. Therefore, we can calculate:
8.68 mol * (6.02 x 10^23 atoms/mol) = 5.23 x 10^24 atoms
So, there are approximately 5.23 x 10^24 atoms in 8.68 mol of copper.
