3. (+)-Tartaric acid has a specific rotation of +12.0°. Calculate the specific rotation of a mixture of 68% (+)-tartaric acid and 32% (-)-tartaric acid. b 1.00 g of sample is dissolved in 20.0 mL of ethanol. Then 5.00 mL of this solution is placed in a 20.0 cm polarimeter tube. The observed deviation angle of rotation is 1,25° counter clockwise. Calculate the specific rotation of the sample.
