State a 0.150 M solution of an enantiomerically pure chiral compound D has an observed rotation of +0.14 in a 1-dm sample container. The molar mass of compound is 149.0 g/mol.
a) Define the specific rotation of D?
b) Define the observed rotation if this solution is mixed with an equal volume that is 0.15 M in L, L is the enantiomer of D?
c) Define the observed rotation if the solution of D is diluted with an equal volume of solvent?
d) Define the specific rotation of D after the diltuion described in part (C)?
e) Define the specific rotation of L, the enantiomer of D, after the dilution described in part C?
