The vapor density of completely dissociated NH4Cl would be

Question

The vapor density of completely dissociated

N H_{4} C l

would be

Options:

A . same as that of NH4Cl

B . double than that of NH4Cl

C . half than that of NH4Cl

D . slightly less than that of NH4Cl

Answer: Option A
:
A
On dissolution of

N H_{4} C l

into

N H_{3} + H C l

number of moles become double. Hence, volume is doubled and therefore, density is halved.
