equation for the dissociation reaction and determine Kp

Ammonium hydrogen sulfide dissociates into ammonia gas and hydrogen sulfide gas.
If we start with a sample of pure NH4HS(s) at 25 degrees Celsius, the total pressure of the gases is 0.658 atm when equilibrium is established. Write an equation for the dissociation reaction and determine the value of Kp.
(Use the lowest possible coefficients.)
