Chemistry

A 0.120 M solution of an enantiomerically pure chiral compound Dhas an observed rotation of 0.24° in a 1-dm sample container. Themolar mass of the compound is 140.0 g/mol.

a) what is the specific rotation of D?

b) what is the observed rotation if this solution is mixed withan equal volume that is 0.15 M in L, L is the enantiomer of D?

c) what is the observed rotation if the solution of D is dilutedwith an equal volume of solvent?

d) what is the specific rotation of D after the diltuiondescibed in part (C)?

e) what is the specific rotation of L, the enantiomer of D,after the dilution described in part C?

f) what is the observed rotation of 100 ml of a solution thatcontains 0.01 mole of D and 0.005 mole of L? Assume a 1 dm pathlength
