How do you solve freezing point depression problems?]
What else can I help you with?
The freezing point of a solution containing 4.12 g of unknown solute in 100 grams of camphor is 166.2 degrees C what is the freezing point depression?
The freezing point depression can be calculated using the formula: ΔTf = Kf * m, where ΔTf is the freezing point depression, Kf is the cryoscopic constant for the solvent (camphor), and m is the molality of the solution. Given that the freezing point of pure camphor is 178.4°C, the freezing point depression is 178.4°C - 166.2°C = 12.2°C. We need to first calculate the molality of the solution using the formula: molality (m) = moles of solute / kg of solvent. First, convert the mass of the solute (4.12 g) to moles, then calculate the molality. Once you have the molality, you can substitute it along with the freezing point depression into the formula to find the cryoscopic constant Kf.
What would the final freezing point of water be if 3 mol of sugar were added to 1 kg of water?
-5.58 C
What is the freezing point of a solution that contains 0.550 moles of Nal in 615 g of water?
The freezing point depression equation is used to calculate the freezing point of a solution. Given the molality of the NaI solution and the molecular weight of water, the freezing point of the solution can be determined.
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
What would be the final freezing point of water be if 3 mol of sugar were added to 1 kg of water?
-5.58 C
What does the depression of the freezing point dependent on?
The depression of the freezing point is dependent on the nature of solvent and concentration of solute.
What is the relationship between freezing point depression and molar mass?
The relationship between freezing point depression and molar mass is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
What is the relationship between the molar mass and freezing point depression of a substance?
The relationship between the molar mass and freezing point depression of a substance is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
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.
The depression of the freezing point is dependent on?
The depression of the freezing point is dependent on the concentration of solute particles in a solution. More solute particles lead to a greater depression of the freezing point.
What is the relationship between the molar mass and freezing point depression in lab answers?
The relationship between molar mass and freezing point depression in lab answers is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
What is the freezing point depression constant for naphthalene?
The freezing point depression constant for Naphthalene is 6.9 degrees Celsius/mhttp://en.wikipedia.org/wiki/Freezing-point_depression
What is the tendency of a solute to change the melting point of a solid called?
The answer is "Freezing point depression" on Apex
What is the freezing point depression constant for water?
The freezing point depression constant for water is 1.86 degrees Celsius per molal.
How can one calculate freezing point depression in a solution?
To calculate freezing point depression in a solution, you can use the formula: Tf i Kf m. Tf represents the freezing point depression, i is the van't Hoff factor, Kf is the cryoscopic constant, and m is the molality of the solution. By plugging in these values, you can determine the freezing point depression of the solution.
What is the freezing point of a solution containing 2.50g of benzene in 120g of chloroform?
Since benzene is the solute and chloroform is the solvent, this is a non-electrolyte solution. The freezing point depression equation is ΔTf = Kf * m, where ΔTf is the freezing point depression, Kf is the freezing point depression constant for chloroform, and m is the molality of the solution. From this, you can calculate the freezing point of the solution.
21.6 g NiSO4 in 1.00 102g Hu2082O what is the freezing point of this solution?
To determine the freezing point of the solution, you need to calculate the molality of the NiSO4 in the H2O solution. Once you have the molality, you can then use the formula for freezing point depression to find the freezing point. This formula is ΔTf = Kf * m, where ΔTf is the freezing point depression, Kf is the freezing point depression constant (for water it is 1.86 °C kg/mol), and m is the molality of the solution. Finally, add the freezing point depression to the normal freezing point of water (0°C) to find the freezing point of the solution.
