A sample of 7.70 L of NH3 (ammonia) gas at 22 °C and 735 torr is bubbled into a 0.500 L solution of 0.400 MHCl (hydrochloric acid).
The Kb value for NH3 is 1.8×10-5 .
Part A Assuming all the NH3 dissolves and that the volume of the solution remains at 0.500 L, calculate the pH of the resulting solution. Express your answer numerically to two decimal places.
