This is done the same way as the C2H5NH3Cl. I don't think I need to work this. Just follow my lead on the other problem. The equation you need is
...................NO2^- + HOH ==> HNO2 + OH^-
I.....................0.590.....................0...........0
C...................-x............................x............x
E..................0.590-x....................x...........x
I'll leave it with you.
Post your work if you get stuck.
