Chemistry

A student measured the optical activity of an unknown sugar attwo different concentrations. The results of his measurements areshown below. Given that the sample cell had a path length of 10.0cm, calculate the specific rotation for the unknown sugar. (Hint:Consider each measurement of plane polarized light has a truereading and a \"ghost\" reading 180° from the true reading).
concentration observed rotation 2.00 g sugar in 10.0 mL water+159.1∘
5.00 g sugar in 10.0 mL water +127.8∘
Answer=-105∘ . WHY? Please write out steps
