I am not sure if there is a formula for finding K1 and K2 My

I am not sure if there is a formula for finding K1 and K2. My first inflection point is 24.50, and my second inflection point is 49.00, and the moleculare weight of my unknown acid was calculated to be 105.8g/mol (malonic acid). After making my graph, I found K1 by just dividing 24.50/2=12.25, and for K2 49.00/2 + 12.25 = 36.75. Am I doing this right? Or is there an actual formula I have missed? Thanks for any help.

Solution

YES , u are right k1 will simply the the inflection point /2 and k2 will be K1 + second inflection point /2
