15, 16 how do i do these? ВІ 15.03 pts.) If a sample contains 83% of the Renantiomer and and 17% of the Senantiomers what is the enantiomeric excess of the mixture. EE - 100% 16.03 pts.] What is the specific rotation of a sample of carvone that is an equal mixture of the Rand S enantiomers (R- carvone has a specific rotation of -61)?
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...
