Write the balanced chemical equation for the reaction taking place in the flasks for part 1.  From the mass of KHP, calculate the moles of KHP used for each of 3 trials.  Using the moles of KHP in each flask, use stoichiometry to calculate the moles of NaOH that were used to reach the equivalence point in each flask.  Finally, calculate the molarity of your NaOH solution using the moles of NaOH and the volume of titrant used for each trial individually and averaging molarity for your trials.  The average molarity of your NaOH should fall between 0.17 and 0.25 M.  If your value does not fall in this range, there is definitely something wrong and you are encouraged to take your work to your instru..
