How many times heavier is chlorine gas compared to air?

Chlorine gas is denser than air, and its molecular weight plays a crucial role in this comparison. The molecular weight of air is approximately 29 g/mol, while the molecular weight of chlorine (Cl2) is about 70.9 g/mol. To find out how many times heavier chlorine is compared to air, you can divide the molecular weight of chlorine by that of air.

When you do this calculation (70.9 g/mol divided by 29 g/mol), the result is approximately 2.44. This indicates that chlorine gas is about 2.5 times heavier than air.

Thus, the answer indicates that chlorine gas is significantly denser than the surrounding atmosphere, which has implications in various applications such as handling and storage, where the density affects how the gas behaves and disperses.
