A chemist needs to neutralize a 2.6 M solution of HCI. If there are 420 mL of solution, what volume, in Liters, of a 2.0 M NaOH solution would have to be used? (Hint: You will need to write out the chemical equation and balance it first.) Be sure to report your answer to the correct number of significant figures. Do not report the units (L) in your answer.

An analytical chemist weighs out 0.264 g of an unknown diprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. He then titrates this solution with 0.1900M NAOH solution. When the titration reaches the equivalence point, the chemist finds he has added 18.5 mL of NaOH solution. Calculate the molar mass of the unknown acid. Round your answer to 3 significant digits. x10 mol
