(+)- has a specific rotation of +52 degree. Suppose a mixture of (+) and (-) and (-) is analyzed by polarimetry and the observed rotation is +48 degree. What is the percentage excess (%) of the (+) isomer in the mixture? Express your answer in a whole number and use no units Assume a 1g sample was discussed in 1 mL water and the sample cell was 1 cm long.
