(1 pt.) You perform a titration and obtain the following data. Calculate the molarity of the sodium hydroxide solution. Show your work in your notebook. Note: You will receive O credit if you solve this problem with MiV1 M2V2 . Concentration of HC2H302: 0.120 M . Volume of HC2H302 dispensed at the endpoint: 25.20 mL .Volume of NaOH dispensed at the endpoint:24.00m Do not write anything in this text box. It is serving as a placeholder for the in-lab notebook check.*** Your Answer:

Explanation / Answer

NaOH(aq) + HC2H3O2(aq) ---------------> NaC2H3O2(aq) + H2O(l)

1 mole          1 mole

NaOH                                                     HC2H3O2

M1   =                                                       M2   = 0.12M

V1   = 24ml                                                V2   = 25.2ml

              M1V1   = M2V2

                  M1   = M2V2/V1

                           = 0.12*25.2/24   = 0.126M

molarity of NaOH   = 0.126M >>>>answer
