Hx (aq) + NaOH --> H2O (l) + Nax(aq)

Calculate number of moles of NaOH that was needed to neutralize all of the acid. 

Use stoichiometry to determine how many moles of acid must have been present in the titration experiment.

Use the mass of the acid and the moles of the acid present in the titration to determine the molar mass.

Calculate the molar mass.  

Mass unknown = 0.3089g

concentration NaOH = 0.3089M

intial mL in buret = 1.44

end point mL in buret = 13.72
