11 degrees at 10cm
rotation of sucrose is 1
C=.171
Tength of the light path, and the wavelength of the A standard formula is used to convert observed into "specific rotations" Tal a physical property tl be found in tables of physical properties of chemical compounds. al- 0 - measured rotation in angular degrees c = concentration in grams per milliliter of solution = cell length in decimeters D = wavelength of light, usually the D* line of a sodium...

a. In this equation for specific rotation of a solution: a is the observed rotation in degrees, is the path length in decimetres, c is the concentration in g mL-1, Tis the temperature at which the measurement was taken in °C, and A is the wavelength in nanometres. You used variable path lengths for the polarised light (589 nm) to pass through, and you obtained the fol solutions (A, B, C, D and E) at variable concentrations. observed rotation data...
