Ammonium carbamate (NH2COONH4) is found in the blood and urine of mammals. At a temperature of 343 K, Kc = 0.071 for the following equilibrium:NH2COONH4(s) <=> 2 NH3(g) + CO2(g).If 10.2 g of ammonium carbamate is introduced into a 0.500 L container, what is the total pressure inside the container at equilibrium?
