How can the freezing point depression method be used to calculate the molar mass of a solute in a solution?
The freezing point depression method can be used to calculate the molar mass of a solute in a solution by measuring the decrease in the freezing point of the solvent when the solute is added. By knowing the freezing point depression constant of the solvent and the amount of solute added, the molar mass of the solute can be calculated using the formula: molar mass (freezing point depression constant molality) / freezing point depression.

How can one determine the molality of a solution using the freezing point depression method?
To determine the molality of a solution using the freezing point depression method, you need to measure the freezing point of the pure solvent and the freezing point of the solution. By comparing the two freezing points, you can calculate the change in temperature. Using the formula T Kf m, where T is the change in temperature, Kf is the cryoscopic constant of the solvent, and m is the molality of the solution, you can solve for the molality of the solution.

What are some problems with the use of water as a solvent for determining the molecular mass of an unknown using the freezing point depression method?
One problem is that impurities in the water can affect the accuracy of the results. Additionally, water's freezing point is 0°C, which may limit the range of compounds that can be accurately measured using the freezing point depression method. Lastly, the specific heat capacity of water is relatively high, which can make it slower for the solution to reach thermal equilibrium.
What is the method to calculate the concentration of the salt solution in parts per million?
