Homework Help: Concentration and pressure problem. Need help!

  1. Nov 15, 2005 #1
    Ammonium carbamate (NH2COONH4) is found in the blood and urine of mammals. At a temperature of 442 K, Kc = 0.043 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?

    Correct answer 2.40E1 (2.40 * 101)

    Concentration of NH2COONH4: 0.2613

    If someone would help me, I would very much appreciate it.

    Concentration problem. Need help!

    Ammonium carbamate (NH2COONH4) is introduced into a 0,4 L container, at a temperature of 37 ÂșC, Kc = 4,1 for the following equilibrium:
    NH2COONH4(s) <=> 2 NH3(g) + CO2(g).
    What is total of ammonium carbamate is introduced into a 0.400 L container at equilibrium?
