Solid Ammonium hydrogen sulfide (NH4HS) is introduced into a 2.00 L flask, and the flask is sealed. If this solid decomposes according to the equation
NH4SH(s)-->NH3(g) + H2S(g), Kp=0.108 at 25 degrees C
What is the minimum mass of Ammonium hydrogen sulfide that must be present in the flask initially if equilibrium is to be established at 25 oC?
