temperatures as error-free; R = 8.3145 J mol-1 K-1) 4. (3) A solution of a different sugar, bashanose, is prepared by dissolving 23.71 g of bashanose in
water and bringing the volume to 0.100 L in a volumetric flask. The optical rotation observed at lD
for this solution in a 0.200-m polarimetry cell at 25°C is 14.7°. Calculate the specific rotation of
bashanose (units deg mL g– 1 dm– 1) at this wavelength and T....
