A saponification value of 190 milligrams of potassium hydroxide per gram corresponds to a mean molecular weight of the triglyceride of about

  • A.560
  • B.1400
  • C.885
  • D.190

Answer: C

Three moles of the alkali of mass fifty-six saponify one mole of triglyceride, so the molecular weight is three times fifty-six thousand divided by one hundred and ninety. A high saponification value therefore means short chains.
