Ecdysone is an insect hormone that controls molting. in a polarimetric experiment, 70.00 mg of ecdysone was dissolved in 10.00 ml of chloroform, and the solution was placed in a 2.0 cm path-length cell. the optical rotation was measured at 20 °c using the yellow sodium d line near 589 nm wavelength. if the rotation observed was of +0.087°, calculate the 20davalue for ecdysone.
