How many iodine atoms are present in 4 molecules of carbon tetraiodide (CI_4)?

• A. 12
• B. 4
• C. 16
• D. 8

Answer: (C)

Verified step by step guidance

1. Identify the chemical formula of carbon tetraiodide, which is \(\mathrm{CI_4}\). This means each molecule contains 1 carbon atom and 4 iodine atoms.
2. Determine the number of iodine atoms in one molecule of \(\mathrm{CI_4}\), which is 4.
3. Since the problem asks for the number of iodine atoms in 4 molecules, multiply the number of iodine atoms per molecule by the number of molecules: \$4 \times 4$.
4. Set up the multiplication as \$4 \times 4 = 16\( to find the total number of iodine atoms in 4 molecules of \)\mathrm{CI_4}$.
5. Conclude that there are 16 iodine atoms present in 4 molecules of carbon tetraiodide.
