H2 SO4(aq) + 2 NaOH(aq) → Na2 SO4(aq) + 2H2O(1) A titration is performed on a sample containing sulfuric acid (H2SO4) to assess its concentration. 4.09 mL of this sample are used to perform the titration. If 15.9 mL of a 1.00 M NaOH solution are required to reach the endpoint of the titration (neutralize all of the sulfuric acid), what was the molarity, of sulfuric acid in that sample?
