Question

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?
chlorine
oxygen
bromine
silver

Answer 1

Answer: Option (d) is the correct answer.

Explanation:

As it is known that density is the amount of mass divided by the volume.

Mathematically,     Density = $\frac{mass}{volume}$

Since, mass is directly proportional to density. Hence, more is the mass of an object more will be its density.

At room temperature chlorine exists as a gas and its molar mass is 35 g/mol.

At room temperature oxygen exists as a gas and its molar mass is 32 g/mol.

At room temperature bromine exists as a liquid and its molar mass is 80 g/mol.

At room temperature silver exists as a solid and its molar mass is 108 g/mol.

As the mass of silver is greater and it exists as a solid at room temperature. Hence, it will be most dense in nature.

Therefore, we can conclude that out of the given options silver substance is most likely the most dense.

Answer 2

The answer is silver. Silver is the most dense, it's a solid so it is more compact and is obviously the most likely to have more mass to it.
