49. Solving a chemistry problem

2. Perform a quantitative analysis of the glucose solution for using the polarimetry method and draw a conclusion. After measuring the angle of rotation three times after filling the polarizing tube, we obtained the average of three measurements equal to + 22.60,l=215.5 mm 52.7– specific rotation of glucose in degrees.
Answer: the quantitative content of glucose in the solution is 39.9%
