The vapour density of fully dissociated ...

The vapour density of fully dissociated `NH_(4)Cl` would be

A

Slightly less than half of that of ammonium chloride.

B

Half of that of ammonium chloride.

C

Double that of ammonium chloride

D

Determined by the amount of solid ammonium chloride used in the experment.

Text Solution

Verified by Experts

The correct Answer is:
B
`("normal mol. mass")/("exp.mol.mass")=1+alpha`
`NH_(4)CIhArrNH_(3)+HCI alpha=1`
`"exp Mol. Mass"=("Normal mol mass")/(2)`
