2 gram potassium bitartrate are put into a 250ml flask. 150ml water is added. The solution is stirred and left to settle.

the solution if filtered through a dry funnel into a 250ml breaker. 25ml of this solution was placed into 4 different flasks each. Approximately 11.5666667ml of NaOH was added to each flask. What is the concentration of the HC4H4O6-? (Asked on the right side of the table)
