3. Explain why the experimentally determined values for the specific rotation vary from literature values, if necessary. Conclusions: The relationship between sample height and optical rotation is direct. The angle of rotation when the sample height is 12.0 cm is 7.4231 based on the equation listed in the graph. v0.1721 Optical Rotation in Degrees 7 10 11 Height of Liquid (cm) 2. For Part 2, generate a plot of the calculated concentration values in g/mL vs. optical rotation in degrees, as you did above. Based on your data, what is the relationship between optical rotation and condentration? 20 1 2002901 0.999 16 14 Optical Rotation in Dept 0.001 0.003 0.005 0.000 DO 0.003 0.004 Concentration in /ml The relationship between optical rotation and concentration is direct, as the concentration increases so does the optical rotation.
