If the measured rotation of the plane of polarized light by a glucose solution is 12.2° using a 20cm tube what?
is the concentration (g/100ml) of the glucose solution? Specific rotation of glucose +52.7° .
Hi there could someone please explain this to me and how to get the answer?! I am looking through my notes but can't quite figure it out ! I am doing introductory food chemistry : food constituents. Thanks in advance !

20 cm is 2 decimeter
specific rotaiton is for 1 dec path length at 1 g/100 ml
12.2 = 52.7 * 2 dec * (actual conc in g/100 ml)
12.2/52.7*2 = 0.112 g/100 ml
