2.10 g of an unknown compound was dissolved in 15.00 mL of ethanol. The sample was placed in a 10.0 cm cell in a polarimeter and the angle of rotation was determined to be -18.48°. What is the specific rotation of this unknown (show work) and specify if the compound is levorotatory or dextrorotatory?
