What volume of 0.250 M nitric acid is needed to neutralize 17.35 mL of 0.195 M KOH solution?
Kyle LaPage Allison Moore (12129)-Tues./12pm Partner: Ian Kim and Whitney Bowman 2/16/16 Post lab exp. 3 1. a. mass of stearic acid: 8.24g b. mass of first addition of unknown fatty acid: 1.03g c. mass of second addition of unknown fatty acid: 0.99g d. freezing point of stearic acid: 68.25 ⁰C e. Freezing point after 1 unidentified sample addition: 65.45 ⁰C f. Freezing point after 2 unidentified sample addition: 63.05 ⁰C 2. a. molality of unidentified sample b. moles of unidentified sample c. molar mass of unidentified sample 3. The unidentified sample is most likely Lauric acid because it is the closest in molar mass to our calculated value. It has a molar mass of 200.31 g/mol. While out calculated value is at about 212.18g/mol. 4.
