solve for pH , no intermediate rounding at ALL

An analytical chemist is titrating 202.3 mL of a 0.2400M solution of ammonia (NH ) with a 0.6800M solution of HC104 The p K, of ammonia is 4.74. Calculate the pH of the base solution after the chemist has added 82.5 mL of the HCIO solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume?of HCIO solution added Round your answer to 2 decimal places.
