7. Calculate the pH of 100 mL of 0.30 M NH₃ after the addition of 4.0 g of NH₄NO₃. Assume that the volume remains constant.
8. Calculate the pH of the following solutions:
a) Adding 20.0 g NH₄Cl to 1.0 L of 0.50 M NH₃
b) Mixing 50.0 mL 1.0 M NH₃ and 150 mL 1.0 M NH₄Cl
c) Mixing 25.0 mL 1.0 M NH₃ and 25.0 mL 0.40 M HCl
