The molar mass of a solute can be determined using freezing point depression by measuring the change in freezing point of a solvent when the solute is added. By using the formula Tf Kf m, where Tf is the change in freezing point, Kf is the cryoscopic constant of the solvent, and m is the molality of the solution, the molar mass of the solute can be calculated.

How is the determination of molar mass achieved through the phenomenon of freezing point depression?
The determination of molar mass is achieved through freezing point depression by measuring the decrease in the freezing point of a solvent when a solute is added. This decrease is directly proportional to the molality of the solute, allowing for the calculation of the molar mass of the solute using the formula: Tf Kf m i, where Tf is the freezing point depression, Kf is the cryoscopic constant of the solvent, m is the molality of the solute, and i is the van't Hoff factor.
How do you calculate the molality from the freezing point?
To calculate molality from the freezing point, you can use the formula: molality (Kf Tf) / molar mass of solute. Here, Kf is the freezing point depression constant, Tf is the change in freezing point, and the molar mass of the solute is the mass of the solute in one mole.
How is molar mass determination achieved through the process of freezing point depression?
Molar mass determination through freezing point depression involves measuring the decrease in freezing point of a solvent when a solute is added.

By using the formula Tf Kf m, where Tf is the freezing point depression, Kf is the cryoscopic constant of the solvent, and m is the molality of the solution, you can then solve for the molality. Finally, by using the formula molality moles of solute / kilograms of solvent, you can determine the moles of solute present and calculate the molar mass of the substance.
What is the molar freezing point constant?
The molar freezing point constant (Kf) is a physical constant that represents the amount by which the freezing point of a solvent is lowered for each mole of solute dissolved in it. It is specific to each solvent and is used in calculating the freezing point depression in colligative properties.
How is molar mass determined using colligative properties?
You can calculate the molecular mass using freezing point depression or boiling point elevation using the formula: mols solute= change in BP (or FP) x kg solvent / Kb (or Kf) /i Where Kb and Kf are constants and i is number of ions (or 1 if covalent) Then take mols solute (calculated) and divide into grams solute (recorded)
