Task 3.50
A sugar solution with a concentration of 0.25 g / cm3, 18 cm thick, rotates the plane of polarization of monochromatic light by an angle of 30 °. Another solution 16 cm thick turns the polarization plane of this same light by an angle of 24 °. Determine the concentration of sugar in the second solution.
