Jack began his lab by accurately weighing 10.81 g of KHP, dissolving it

carefully in the beaker, transferring it quantitatively to the volumetric

flask and carefully topping up with water so that the bottom of the

meniscus was exactly on the graduation mark of a 500 cm3 volumetric flask.

Jack then filled the burette with KHP and placed 20.00 cm3 of NaOH in the

conical flask. He carried out a rough titration and got 20.55 cm 3, he

then car out three further titrations obtaining values of 20.40 cm3, 20.15

cm3, 20.25cm3.

What is the molarity of the NaOH solution?
