Question:

Safrole is contained in oil of sassafras and was once used to flavor root beer. A 2.39-mg sample of safrole was dissolved in 103.0 mg of diphenyl ether. The solution had a melting point of 25.70°C. Calculate the molecular mass of safrole. The freezing point of pure diphenyl ether is 26.84°C, and the freezing-point-depression constant, Kf, is 8.00°C/m.
