1. Understand the Formula:

* Tetrafluoride refers to a compound with four fluorine atoms per molecule. However, we don't know the central atom. To proceed, we'll assume you meant carbon tetrafluoride (CF₄).

2. Use Avogadro's Number:

* Avogadro's number (6.022 x 10²³) tells us the number of particles (atoms, molecules, etc.) in one mole of a substance.

3. Set up the Calculation:

* Moles of CF₄: 3.27 moles

* Atoms of C per molecule of CF₄: 1 atom

* Atoms of C per mole of CF₄: 1 atom/molecule * 6.022 x 10²³ molecules/mole = 6.022 x 10²³ atoms/mole

4. Calculate:

* Total atoms of C: (3.27 moles CF₄) * (6.022 x 10²³ atoms C/mole CF₄) = 1.97 x 10²⁴ atoms of C

Therefore, there are approximately 1.97 x 10²⁴ atoms of carbon present in 3.27 moles of carbon tetrafluoride (CF₄).
