Homework Help: Chemistry

Posted by Liz on Thursday, August 7, 2014 at 12:24pm.

I am to do an equilibrium constant lab and I am supposed to only find the Kc value. i have to find the equilibrium constant for NaHCO3 (s) <--> NaOH (s) + CO2 (g) at 800K. The partial pressure in the bulb reads 420 kPa on the manometer, 1 gram of NaHCO3 was added to the bulb and the bulb's volume is 500 mL.

I'm not sure if I did this correct but I used the PV=nRT formula and solved for n and I got 0.00316 mols. Then I used the c=n/v formula to find the concentration, and i got 6.3x10^-6. I don't know where to go from here to find the Kc value.
