5. The concentration of an unknown sample of sulfuric acid was determined by the method used in this experiment, using two sets of titrations. In the first titration the sodium hydroxide was standardized by titrating 0.1355g of oxalic acid dihydrate (molar mass - 126.07g/mole) with 25.30mL of sodium hydroxide solution. In the second titration 20.00mL of the unknown sulfuric acid solution was titrated with 22.85mL of the sodium hydroxide solution. What was the concentration of the sulfuric acid? (Show your work!!)
