If a 28 mLs of a 0.25 molar NaOH solution is used to titrate 14 mLs of a nitric acid to its phenolphthalein endpoint, what is the molar concentration of the acid?

mL x M = mL x M (Technically this is the dilution equation but you may use it in titrations in which the ratio of the titrant to the unknown solution is 1:1).
