What is chlorine gas?

Chlorine is a yellow-green gas at room temperature. Chlorine has a pungent, irritating odor similar to bleach that is detectable at low concentrations. The density of chlorine gas is approximately 2.5 times greater than air, which will cause it to initially remain near the ground in areas with little air movement.

How do you make chlorine gas?

Chlorine production
1. Chlorine gas can be produced by extracting from natural materials, including the electrolysis of a sodium chloride solution (brine) and other ways.
2. Chlorine can be manufactured by the electrolysis of a sodium chloride solution (brine), which is known as the Chloralkali process.

How do you find the number of molecules at STP?

To find the number of molecules in a gas sample, given the pressure, volume, and temperature of the sample:
1. Figure out how many moles of CO2 gas you have. …
