Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC3H,04. This is often written in shorthand notation as KHP. How many grams of KHP are needed to exactly neutralize 29.3 mL of a 0.557 M sodium hydroxide solution ? grams KHC3H404

A solution is prepared by taking 7 ml of 5.9 M HCl and diluting it to 113 ml. Then 15 ml of that solution is removed a diluted to 27 ml. What is the molarity of the final solution? (Do not include units in your answer. If you round during your calculation make sure to keep at least 3 decimal places. Report your answer to 2 decimal places.)
