Optical Activity

A solution of decimeter length has concentration $500\mathrm{ }\mathrm{k}\mathrm{g} {\mathrm{m}}^{-3}$ and rotates the plane of polarization by ${24}^{\mathrm{o}}$. Specific rotation of the solution is:

$10 \mathrm{g}$ of optically active pure fructose was in an aqueous solution diluted with $500 \mathrm{ml}$ water and placed in a polarimeter tube $20 \mathrm{cm}$ long. The measured optical rotation was $–5.20°$. To this solution, $500 \mathrm{ml}$ of a solution containing $10 \mathrm{g}$ of racemic fructose is added. Find the change in specific rotation?
