optical activity problems.. please show all steps i dont
understand
You have a sample (Sample X) which is a mixture of +/- Carvone. The solution was made by dissolving 4.50 g of the sample in enough methanol to bring the volume of solution to 10,0 ml. Some of the solution is placed in a 100 cm polarimeter cell and its optical rotation is measured at 25°C using light of the sodium D line wavelength (589.6 nm). The observed rotation is...

Please answer the following questions/fill in the data tables based on the following experiment. EXPERIMENTAL PROCEDURE:...
Please answer the following questions/fill in the data tables based on the following experiment. EXPERIMENTAL PROCEDURE: Place sodium hydroxide (2.500 g) in a 100 mL Erlenmeyer flask and add water (25.0 mL) and ethanol (20.0 mL). Add a magnetic stirrer bar and stir until all the NaOH has dissolved. To a second reaction vessel, add benzaldehyde (2.650 g, 0.025 mol) and acetone (0.725 g, 0.0125 mol). Add approximately half of the aldehyde-ketone solution to the sodium hydroxide solution, and stir...

1. Percent Enantiomerie Excess (ee) is given by the equation if in moless (The difference between Rand S isomers/sum of R & S isomer) - 100. Thus, the sample prepared by Dr. Z. Evans in the PSB 340 Lab contained 12.8 moles of isomer and 3.2 moles of the S isomer. a. Which isomer is in excess in Dr. Evans product? 3.2 moles b. By how much: 12.8 - 3.2 x100 c. What is the percent ce? 2. Enantiomeric Excess...
