(LO 11.4.2) A sample of KHP weighing 0.268 g is titrated with a NaOH solution. If 12.68 mL of NaOH are needed to reach the endpoint, the concentration of the NaOH solution is MM(KHP) = 204.22 g/mol MM(NaOH) = 40.00 g/mol Your Answer: Answer A Question 14 units Retake question (LO 11.1.5, 11.4.2) A sample of KHP weighing 0.268 g is titrated with NaOH solution and it takes 12.65 mL to reach the endpoint. If the next sample of KHP weighs 0.413 g, a reasonable expectation for the endpoint volume for the second sample is mL

Both questions involve titration, where you'll determine the concentration or volume of NaOH required to neutralize a known amount of KHP (potassium hydrogen phthalate). The calculations involve molar mass and stoichiometry to determine the unknown quantities.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd62f153a-5fff-4ab2-99fd-0b9d33305ca9%2Fa9620027-0ef7-4fc7-bbef-5652d0df458a%2F2wn1nqm_processed.jpeg&w=3840&q=75)
