A student makes a standard solution of sulfuric acid by taking 10.00 mL of a super-concentrated stock solution and diluting it to 5.00 L. He then standardizes the diluted solution by titrating 30.00 mL with 34.68 mL of a 0.2458 M solution of KOH. What is the concentration of the stock solution and the standard solution?
