Dear student,
The reaction for the same is given by:
NH_{4}SH\rightleftharpoons NH_{3}+H_{2}O
The equilibrium constant is given by:
K_{p}=\frac{45}{60}=0.75
For finding out the total pressure at equilibrium, we would also need the state of water that is produced/the partial pressure of water.
Regards
Sumit
