Consider the titration of 100.0 mL of 0.100 M H2NNH2 (Kb = 3.0 10-6) by 0.200 M HNO3. Calculate the pH of the resulting solution after 100.0 mL of HNO3 have been added. I know the pH is 1.301029996 I don't know how many significant figures to go to. Please give the answer in the correct number of sig figs. (Hint: I have tried 1, 1.3, and 1.30. None of them are correct.)
