Sodium hydroxide is used extensively in acid-base titrations because it is a strong inexpensive base. A sodium hydroxide solution was standardized by titrating 27 mL of 0.1628 M standard hydrochloric acid. The initial buret reading of the sodium hydroxide was 2.44 mL, and the final reading was 39.39 mL. What was the molarity of the base solution?

HCl + NaOH ==> NaCl + H2O
Since this is a 1:1 reaction, one may use this formula.
mL x M = mL x M
mL NaOH = 39.39 - 2.44
