Homework Help: CHEM HELP!

Posted by student on Monday, March 12, 2012 at 10:35pm.

NH4HS<-->NH3+H2S

What is the minimum mass of NH4HS that must be added to the 5.00-L flask when charged with the 0.300g of pure H2S, at 25C to achieve equilibrium??

Kp=.120 at 25C
initial pressure of H2S in flask = .0431atm
partial pressures of H2S and NH3
.326, .369
mole fraction of H2S =.531

I used the ideal gas law but still recieve the wrong answer. Anyone can help please?
