ViviThe 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?
Molar mass is determined using colligative properties, such as boiling point elevation or freezing point depression, in a process called cryoscopy or ebullioscopy. By measuring the change in the boiling or freezing point of a solution compared to the pure solvent, the number of particles (i.e., molecules) present in the solution can be calculated. From there, the molar mass can be determined using the formula Molar Mass = (RT)/(K∆T), where R is the gas constant, T is the temperature, K is the colligative property constant, and ∆T is the change in temperature.
What temperature is manganese at freezing?
The freezing point of sodium permanganate is 36 degrees Celsius. This is an inorganic compound that has the chemical formula of NaMnO4. Its molar mass is 141.9254 grams per mole.
The freezing point and boiling point for matter is a constant Explain this meaning of constant?
The constant freezing and boiling points of a substance means that under normal atmospheric pressure, the substance will always freeze at the same temperature and boil at the same temperature. This is a characteristic property of the substance and helps in identifying and classifying different materials.
What information is most useful to determine the solution that has a lower freezing point?
To determine which solution has a lower freezing point, you need the concentrations of solute in each solution and their respective properties (molal freezing point depression constants). The solution with the higher concentration of solute and lower molal freezing point depression constant will have the lower freezing point.
What are freezing and boiling point of 0.1 molar solution of CaCl2 in water?
The influence is extremely low - apprpox. 0,05 0C.
