1. Find the molar mass of copper:
* The molar mass of copper (Cu) is approximately 63.55 g/mol.
2. Calculate the number of moles of copper:
* Number of moles = mass / molar mass
* Number of moles = 8 g / 63.55 g/mol
* Number of moles ≈ 0.126 mol
3. Use Avogadro's number to find the number of atoms:
* Avogadro's number is 6.022 x 10^23 atoms/mol
* Number of atoms = number of moles x Avogadro's number
* Number of atoms ≈ 0.126 mol x 6.022 x 10^23 atoms/mol
* Number of atoms ≈ 7.59 x 10^22 atoms
Therefore, there are approximately 7.59 x 10^22 atoms in 8 grams of copper.
