I'm having trouble with part b) since I can't find the new H3O+ concentration. How would I calculate it?

You are given the initial pH.

Now you must consider what will happen to the equilibrium of this system after the addition of H3O+. This means you will set up an ICE table where the initial concentration of H3O+ is now not zero, but 0.65 umol.

The resulting equilibrium concentration of H3O+ can be used to find the new pH.
