The dielectric constants of solutions of chlorobenzene, nitrobenzene and o-dinitrobenzene in polar solvents have been measured. Using Onsager's equation, the dipole moments of the solutes have been calculated and compared with those obtained from measurements in non-polar solvents. The method is then applied to the determination of the moment for urea in 20 weight % water-acetone and in pure water. The moment in the former is 6.25 debyes, and in the latter is 4.2 debyes.
