1. Understanding the Formula
* BF3: This formula tells us each molecule of boron trifluoride contains one boron atom (B) and three fluorine atoms (F).
2. Moles and Molecules
* Avogadro's Number: One mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, etc.).
3. Calculation
* Fluorine atoms per molecule: 3
* Molecules: 3
* Total fluorine atoms: 3 molecules * 3 fluorine atoms/molecule = 9 fluorine atoms
4. Converting to Moles
* Moles of fluorine: 9 fluorine atoms / (6.022 x 10^23 atoms/mole) = 1.49 x 10^-23 moles
Answer: There are approximately 1.49 x 10^-23 moles of fluorine in 3 molecules of boron trifluoride.
