A solution of sodium hydroxide is standardized against potassium hydrogen phthalate (molecular mass = 204.224 g mol-1). From the following data, calculate the molarity of the NaOH solution. The mass of the KHP is 0.7840 g. Before the titration the buret reading was 0.8400 mL and afterwards it was 39.20 mL. A 85.12 mL sample of a solution of sulfuric acid, H2SO4, is neutralized by 59.82 mL of the NaOH solution from the problem above. Calculate the molarity of the sulfuric acid solution.

Walter White requires a sulfuric acid (Strong acid) solution to use in a very important synthetic reaction. He finds a bottle labeled H2SO4, but by some strange turn of events, he cannot remember the concentration. He decides to perform a titration to determine the concentration of the H2SO4. He pours 22.20 mL of his unknown sulfuric acid solution into a flask and finds that it requires 29.50 mL of 0.57 M KOH (strong base) to reach the endpoint. What is the concentration of Walter White's sulfuric acid solution? (Enter your numeric answer only, do not use scientific notation, enter 2 decimal places with your answer) For reference: KOH = 56.106g/mol H2SO4= 98.079g/mol Avagadro's number 6.022x1023
