1. Determine the number of molecules:
* One mole of any substance contains Avogadro's number of particles (6.022 x 10^23).
* So, 3.79 mol of CCl4 contains (3.79 mol) * (6.022 x 10^23 molecules/mol) = 2.28 x 10^24 molecules of CCl4.
2. Determine the number of atoms per molecule:
* Each molecule of CCl4 has 1 carbon atom and 4 chlorine atoms, for a total of 5 atoms.
3. Calculate the total number of atoms:
* Multiply the number of molecules by the number of atoms per molecule: (2.28 x 10^24 molecules) * (5 atoms/molecule) = 1.14 x 10^25 atoms.
Therefore, there are 1.14 x 10^25 atoms in 3.79 mol of carbon tetrachloride.
