Can't figure out why I'm getting an impossibly small amount of NO2...using Kc from 5G.2. Could someone outline the solution? thanks.

I believe if you are calculating x using the information from Table GE.2, the values you would get for x are 1.47x10^-2 or 6.81x10^-3. But you would use 1.47x10^-2 since anything around 10^-3 is too small (I might be wrong about that, but thats my general rule of thumb lol)

which value of K are you using from the table? the inverse of 6.1*10^23?
EDIT: i believe the textbook i have has a typo for the Kc of dinitrogen tetroxide to nitrogen dioxide ... the Kc should be 6.1*10^-3 not 23 lol
