Answer 1

Correct choice: "It is made up of 11 total atoms of 3 different elements."

Explanation: the formula lists how many atoms of each element are in one molecule. For example, C3H7Cl means 3 carbon + 7 hydrogen + 1 chlorine = 11 atoms in total, and there are 3 different element types (C, H, Cl). The formula does not mean a single atom, nor does it specify the atoms' geometric arrangement.
