An empty 5.00-L flask is charged with 0.250 g of pure H2S(g), at 25 ∘C.

What is the initial pressure of H2S(g) in the flask? 3.59*10^-2 atm

In addition to the H2S already present in the flask, solid NH4HS is added until there is excess unreacted solid remaining.

a) What are the partial pressures of NH3 and H2S at equilibrium, that is, what are the values of PNH3 and PH2S, respectively?

b)What is the mole fraction, χ, of H2S in the gas mixture at equilibrium?

c)What is the minimum mass of NH4HS that must be added to the 5.00-Lflask when charged with the 0.250 g of pure H2S(g), at 25 ∘C to achieve equilibrium? Express your answer numerically in grams.
