what is meant by the vapour density of a gas? and the vapour density of a gas decreases or increases on dissociation of a gas? and if a gas dissociates into two products, vapour density of the gas halves or doubles?

Dear student,

Vapor density is a term that arises (or should arise) in every HAZWOPER course.  Vapor density is usually introduced along with a variety of other terms that help us to understand the way a chemical can be expected to act in the environment.  While vapor pressure and boiling point are useful in determining how quickly a chemical will produce a vapor or whether the chemical is in its gaseous state when released from containment, vapor density tells us what will happen to that gas or vapor upon release or when entering a container or room where the chemical has been stored.

BEST OF LUCK..!!!!
