At 218 Celsius, Kc = 0.00012 for the equilibrium:
NH4SH (s) <---> NH3 (g) + H2S (g)
Calculate the equilibrium concentrations of NH3 and H2S if a sample of NH4SH is placed in a closed vessel at 218 Celsius and decomposes until equilibrium is reached.
How the Hell do you do this? Steps would be beyond amazing. Thank you for your consideration.

since you start off with the solid the conc NH3 = conc H2S
to make my life easy I am going to call C = [NH3] = [H2S]
Kc = C^2 = 1.2 E-4
C = sqrt( 1.2 E-4) = sqrt(1.2) sqrt(E-4) = 1.1 E-2 moles/Liter
