To determine the number of atoms in 5 moles of chromium (Cr), we can use Avogadro's number, which states that one mole of any substance contains 6.022 x 10^23 entities (atoms, molecules, ions, etc.).
Given:
- Moles of chromium (Cr): 5 moles
Number of atoms = Moles of substance x Avogadro's number
Number of atoms = 5 moles x (6.022 x 10^23 atoms/mole)
Number of atoms = 3.011 x 10^24 atoms
Therefore, there are approximately 3.011 x 10^24 atoms in 5 moles of chromium.
