To determine which substance is most likely the most dense among chlorine (Cl), oxygen (O), bromine (Br), and silver (Ag) at room temperature, we can consider their physical states and densities.
- Oxygen (O): At room temperature, oxygen is a gas with a density of about 1.43 g/L.
- Chlorine (Cl): Chlorine is also a gas at room temperature, with a density of approximately 3.2 g/L.
- Bromine (Br): Bromine is a liquid at room temperature, with a density around 3.12 g/cm³ (or 3120 g/L).
- Silver (Ag): Silver is a solid at room temperature, with a density of about 10.49 g/cm³ (or 10,490 g/L).
Comparing these values, silver (Ag) has the highest density among the substances listed.
Therefore, the most likely candidate for the most dense substance is silver (Ag).
