Identify the chemical formula given: CI_4, which means one molecule contains 1 carbon atom and 4 iodine atoms.
Determine the number of iodine atoms in one molecule of CI_4, which is 4 iodine atoms per molecule.
Multiply the number of iodine atoms per molecule by the number of molecules given: 4 iodine atoms/molecule \times 3 molecules.
Set up the multiplication as an equation: \$4 \times 3$ to find the total number of iodine atoms.
Calculate the product to find the total iodine atoms present in 3 molecules of CI_4.
