Chlorine is how many times heavier than water?

Chlorine is approximately 1.5 times heavier than water. This is based on the relative densities of chlorine gas and water. Chlorine has a density of about 3.2 grams per liter, while water has a density of approximately 1 gram per liter at standard conditions.

When comparing the densities, it becomes clear that chlorine is denser than water, thus indicating that it is indeed heavier in terms of its weight per equal volume. This property is crucial in various applications, such as in water treatment processes, where understanding the behavior of chlorine in relation to water helps in determining the amounts needed for effective disinfection and other chemical processes.
