6)The equation for molarity states that the molarity of a solution is equal to the number of moles of solute divided by the number of liters of solution. In the first equation, the molarity will clearly be equal to 1.0 M, because there are 1.0 moles of NaCl and a solution volume of 1.0 L.

In the first standardization the molarity of a sodium hydroxide solution (NaOH) will be determined by titrating a sample of potassium acid phthalate (KHP; HKC. 8 H 4 O 4) with the NaOH. In the second procedure the standardized NaOH will be used to determine the molarity of unknown monoprotic acid.

Since they know the volume they started out with they can compute the molarity using the calculated mass. Mr. Green was the murderer. I had great results with this lab, even if their lab techniques weren't perfect since the given range for Mr. Green was 0.5 - 1.5M anyway.
