Question

The vapour density of completely dissociated $N{H}_{4}Cl$ would be:

• A. Same as that of
• B. Double than
• C. Half than that of
• D. Slightly greater than

Answer 1

The correct option is C Half than that of

On dissociating $N{H}_{4}Cl$ gives $N{H}_3$ and $HCl$, number of moles becomes double and vapor density is halved.
