Mercury(II) chloride (HgCl2) freezes at 276.1°C and has a freezing-point depression constant Xf of 34.3 K kg moU. When 1.36 g of solid mercury(I) chloride (empirical formula HgCl) is dissolved in 100 g of HgCl2, the freezing point is reduced by 0.99°C. Calculate the molar mass of the dissolved solute species and give its molecular formula. [Pg.481]

Thus the molality, m, of a solution may be determined from the depression of freezing point. If the weight of solute, w, dissolved in 1 kg of solvent is known the molecular mass of the solute may be calculated from the relation M2 = 1000w/m. K iis is called the freezing-point-depression constant for the solvent. It may be readily calculated if the relevant properties of the solvent are known (Table 6.1), thus enabling the freezing-point equation to be used in a convenient form. [Pg.96]

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 weight of safrole. The freezing point of pure diphenyl ether is 26.84°C, and the freezing-point-depression constant, Ky, is 8.00°C/m. [Pg.519]
