3. A 30.00 mL volumo of aquoous sulfuric acid, H,SO., is titrated using 0.200 M NaOH and an indicator that turms color only after all the sulfuric acid protons have reacted with OH ions. The solution turns color when 48.32 mL of base has been added. What is the molar concentration of the sulfuric acid? (Hint: a balanced chemical equation will help)
