(a) What do you understand by the statement that vapour density of carbon dioxide is 22
(b) Atomic mass of chlorine is 35.5 What is its vapour density?
(a) Vapour density of carbon dioxide is 22, it means that 1 molecule of carbon dioxide is 22 heavier than 1 molecule of hydrogen.
(b)
VD = Molecular weight 2
Vapour density of Chlorine atom =35.52=17.75
