Cecil is working with samples of chlorine (Cl), oxygen (O), bromine (Br), and silver (Ag). The samples are all at room temperature. Which substance is most likely the most dense?

At room temperature, chlorine and oxygen are gases, bromine is a liquid, and silver is a solid. Silver has a density of about 10.5 g/cm³, greater than bromine’s roughly 3.1 g/cm³, so silver is most likely the most dense.
