B. Procedure 1. Measure the [a]obs for both a 10.0 % D-glucose solution and a 10.0 % D-fructose solution. 2. Convert each of the measured [a]os to specific optical activity, [a] o 3. Compare your specific activity to published values and calculate your % error. D-glucose [a] 25 = 52.7° D-fructose[a] 2 = -92.4° Measured [a]obs Convert observed to specifc [a]obs → [a] o 25 % error x 100 experimental - theoretical theoretical C. Additional Questions 1.
