Задача 40971.

A sugar solution with a concentration of 0.25 g / cm ^ 3 with a thickness of 18 cm rotates the plane of polarization of monochromatic light by an angle of 30 °. Another solution 16 cm thick rotates the plane of polarization of the same light by an angle of 24 °. Determine the concentration of sugar in the second solution.

Detailed solution with a brief record of the conditions, formulas and laws used in the decision, the conclusion of the calculation formula and the answer.
If you have any questions about the decision, write. I will try to help.
