人工知能を使用せず、すべてを段階的にデジタル形式で解決してください。ありがとう SOLVE STEP BY STEP IN DIGITAL FORMAT DON'T USE CHATGPT 9.- It has been observed that a pure enantiomer has an optical rotation of -0.62⁰ measured in a 1 dm tube with a concentration of 0.4 g/10 mL. Calculate the specific rotation of this molecule.
The specific rotation of the pure (S) form of Ivermectin is +85.0° when measured using light with a 500 nm wavelength. Ivermectin is an expensive component of a popular COVID treatment called NO-FX. To save money, the Trumpharm company makes NO-FX by mixing inexpensive racemic Ivermectin with some enantiomerically pure Ivermectin. A 1.3 g sample of NO-FX is dissolved in 6.0 mL of CHCl3. When placed in a 1 cm cell, the observed rotation at 500 nm is -0.6°. a) What is the specific rotation of the sample? b) Which isomer is in excess and how do you know it is in excess? c) What is the optical purity of the sample?
