a. We will make about 350 mL of approximately 0.2 M NaOH(aq) solution by diluting 6 M NaOH(aq). Calculate the approximate volume in mL of 6 M NaOH(aq) you need to use to make the diluted solution. Round your answer to 2 significant figures, remembering that this is approximate. Record this volume in the space provided and on your Report doc.
b. We want to use about 20 mL of the NaOH(aq) solution in our titration with the KHP. The approximate molarity of the NaOH(aq) solution is 0.2 M. Calculate the approximate mass of KHP that you would need to neutralize 20 mL of this solution. Round your answer to 2 significant figures, remembering that this is approximate. Record this mass in the space provided and on your Report doc.
