The Ideal Gas Law

Q. Ammonium bisulfide, NH4HS, forms ammonia, NH3, and hydrogen sulfide, H2S, through the reaction NH4HS(s)⇌NH3(g)+H2S(g) This reaction has a Kp value of 0.120 at 25 ∘C. What is the minimum mass of NH4HS that must be added to the 5.00-L flask when charged with the 0.250 g of pure H2S(g), at 25 ∘C to achieve equilibrium?
