Hope it helps...

Answer 2

Explanation:

using mole concept

number of moles =given mass/molecular masss

number of moles =given volume /22.4

therefore

given mass/molecular mass=given volume/22.4

2/molecular mass=1/22.4

molecular mass =44.8

molecular mass =2 vapour density

vapour density=44.8/2

=22.4
