1. Understand the Chemical Formula:
* CCl₄ represents one molecule of carbon tetrachloride.
* The subscript "4" indicates there are 4 chlorine atoms in each molecule.
2. Use Avogadro's Number:
* Avogadro's number tells us that one mole of any substance contains 6.022 x 10²³ particles (atoms, molecules, etc.).
3. Calculate the Number of Chlorine Atoms:
* Step 1: Find the total number of CCl₄ molecules in 2.00 moles:
* 2.00 moles CCl₄ × (6.022 x 10²³ molecules/mole) = 1.20 x 10²⁴ CCl₄ molecules
* Step 2: Calculate the total number of chlorine atoms:
* 1.20 x 10²⁴ CCl₄ molecules × (4 chlorine atoms/CCl₄ molecule) = 4.81 x 10²⁴ chlorine atoms
Therefore, there are 4.81 x 10²⁴ chlorine atoms in 2.00 moles of CCl₄.
