17.3 mg sample of an organic compound (a non-electrolyte) was ground up with 420 mg of camphor to form a homogeneous mixture melting at 170.0 oC. What is the apparent formula weight of the organic compound? (Kf of camphor = 37.7 oC/m, m. p. of camphor = 178.4 oC) (Note: This is a freezing point depression problem - note the Kf of camphor - camphor is the solvent.)
