A 0.26 M solution of an enantiomerically pure chiral compound D has an observed rotation of +0.197° in a 1‑dm sample container. The molar mass of the compound is 132.3 g/mol. a. What is the specific rotation of D? b. What is the observed rotation if this solution is mixed with an equal volume of a solution that is 0.26 M in L, the enantiomer of D? c. What is the observed rotation if the solution of D is diluted with an equal volume of solvent?
