observation sheet

extra observations : volume for run 1 will be 9.86ml please convert to L when doing work

question- this graph below is for run 1 which shows the equivalence point and the points dotted 9.86 ml and 9.615 pH are where they are.

what am i missing and need to add more work for question 2 and then how would i do question 3 a+b
