Understanding the Concept
* Avogadro's Number: One mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, etc.). This is known as Avogadro's number.
Calculation
1. Set up the conversion factor:
1 mole F = 6.022 x 10^23 atoms F
2. Divide the given number of atoms by Avogadro's number:
(1.50 x 10^23 atoms F) / (6.022 x 10^23 atoms F/mole)
3. Calculate the result:
≈ 0.249 moles F
Answer: There are approximately 0.249 moles of fluorine in 1.50 x 10^23 atoms of fluorine.
