Thus, is in order,

Le-Chatelier?s principle is not applicable to solid-solid equilibrium.

that means more gases are present
or gets completely dissociated into ammonia gas.

For a diprotic acid, further ionization is difficult,
therefore

Similarly, of

Ammonium acetate is a salt of weak acid and weak base.

Given that,
Putting that values, we get

Given, molecular mass

To dissolve of , water requires

The initial vapour density will be same, it would be

The system initially contains and solid ,
which dissolves as follows

Therefore,
Since, no and were present in solution before the dissolved,

Thus, the equilibrium concentration of these ions will be determined by the amount of salt that dissolves to reach equilibrium
