Answer:

9.79740949850 moles

Explanation:

  • 1 mole = Avogardo's Number <<6.022 E 23 <<particles, atoms, etc.>>
  • This problem can be solved using dimensional analysis by multiplying atoms (5.9E24 atoms) by (1) mole and then dividing the number by Avogardo's number (6.022 E 23 atoms).
  • Note: E = * 10

Side Note: Please let me know if you need any clarifications about this!
