1. Understanding the Compound

* "Tetrabromide" implies a compound with four bromine atoms (Br) attached to something. We need to know the other part of the molecule to determine the number of carbon atoms.

2. Example: Tetrabromomethane

* Let's assume the compound is tetrabromomethane (CBr₄). Here's how we'd solve for the number of carbon atoms:

3. Moles to Molecules

* Avogadro's number: There are 6.022 x 10²³ molecules in one mole of any substance.

* Calculation:

* 4.25 moles CBr₄ * (6.022 x 10²³ molecules CBr₄ / 1 mole CBr₄) = 2.56 x 10²⁴ molecules CBr₄

4. Molecules to Atoms

* Ratio: One molecule of CBr₄ contains one carbon atom.

* Calculation:

* 2.56 x 10²⁴ molecules CBr₄ * (1 carbon atom / 1 molecule CBr₄) = 2.56 x 10²⁴ carbon atoms

Important Note: The answer depends on the specific tetrabromide compound. If you know the specific compound, follow the same steps above, adjusting the ratio of carbon atoms per molecule in step 4.
