A vast assemblage of molecular gas with a mass of approximately 10 3 to 10 7 times the mass of the Sun is called a giant molecular cloud (GMC).GMCs are around 15 to 600 light-years in diameter (5 to 200 parsecs). Whereas the average density in the solar vicinity is one particle per cubic centimetre, the average density of a GMC is a hundred to a thousand times as great.
Chlorine: isolation. Isolation: it is rarely necessary to make chlorine in the laboratory as it is readily available commercially in cylindes.Chlorine is found largely in seawater where it exists as sodium chloride. It is recovered as a reactive, corrosive, pale green chlorine gas from brine (a solution of sodium chloride in water) by electrolyis.
