Define boiling point. Write the formula to determine molar mass of a solute using freezing point depression method. |

Answer» The boiling point of a liquid is defined as the temperature at which the vapour pressure of the liquid becomes equal to the atmospheric pressure. The formula to determine molar mass of a solute using freezing point depression method is M2 = \(\frac{K_fW_2}{ΔT_fW_1}\) Where, M2 = Molar mass of solute in kg mol–1 Kf = Cryoscopic in K kg mol–1 constant ΔTf = Depression in freezing point in K W2 = Mass of solute in kg W1 = Mass of solvent in kg |
