Interpretation Introduction

Interpretation:

The observed rotations are to be determined, and if the optical rotation of a substance studied at only one concentration is zero, then whether it can be concluded as the achiral or racemic mixture or not is to be stated with given concentration, observed rotation, wavelength, path length of the tube, and temperature.
