Need help with the solution 

A 0.213 g sample of solid NH40CONH2 (mw=78.07 g mol-1) is added to an empty 0.500 L flask. The flask is then
sealed and the temperature is kept at 25°C. At this temperature, the solid decomposes as follows:
NH,OCONH, (s) = 2 NH,(g) + CO,(g)
At equilibrium, some solid still remains, and the total pressure in the flask is 0.14 bar. What is Kp at 25°C for this
reaction? Choose the closest value. Express all pressures in bar.
