What is the pH of a 0.0353M solution of NH4F and a 0.0000666M solution of NH4F?

(H^+) of a salt of weak acid + weak base (NH4F is such a salt) is sqrt(KwKa/Kb)

Does ph differ with changes in concentration?

In theory no. In practice, probably so. Since pH = 7 + 1/2 pKa - 1/2 pKb there is no concn term; therefore, it isn't concn dependent.
