An analytical chemist is titrating 102.0 mL of a 0.8400M solution of cyanic acid (HCNO) with a 0.5700M solution of NaOH. The p K of cyanic acid is 3.46. Calculate the pH of the acid solution after the chemist has added 25.74 mL of the NaOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of NaOH solution added. Round your answer to 2 decimal places.

Knowledge Check Question 8 Iffa The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant R. Suppose the osmotic pressure of a certain solution is measured to be 11. atm at an absolute temperature of 349. K. Write an equation that will let you calculate the molarity c of this solution. Your equation should contain only symbols. Be sure you define each symbol other than R. Your equation: Definitions of your symbols: D= 11. atm = 349. K II

The answer was incorrect and I don't understand why
