mols H2S = grams/molar mass = 0.350/34 = 0.0102
Then PV = nRT.
P = nRT/V = [0.0102*0.08206 x (273+25)]/5.00 = ? atm
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.
An empty 5.00-L flask is charged with 0.350 g of pure H2S(g), at 25 ∘C.
What is the initial pressure of H2S(g) in the flask?
