If a substance is known to have a specific rotation of -89.3 deg mL/g dm, what is the concentration (in g/mL) of a solution that would give an observed rotation of -25.5 degrees, if the path length of the sample tube was 2.00 dm? (Hint: Rearrange the specific rotation calculation formula)
Name each alkene and specify its configuration by the E,Z system. (Be sure to indicate double bond stereochemistry using (E)/(Z) notation. It is not necessary to use italics in writing compound names.)

Note: enantiomers have similar physical properties (mp, density, solubility), and same [a], but with different signs ( - or +). Practice: 1.2 gm sample of cocaine, [a], = -16º, was dissolved in 7.5 mL of chloroform and placed in a sample tube having a pathlength of 5 cm. what was the observed rotation in degrees?
The specific rotation, [a]p, for (-)-2-butanol is +14. What is the observed rotation for a solution of 2.5 g of (-)-2-butanol in 10 mL of water in a sample tube having a pathlength of 10 cm? degrees. The observed rotation of a solution of 0.75 g of a compound in 10 mL of water is -4.6 degrees. If the pathlength is 10 cm, what is the specific rotation of the compound?
