What is the freezing point depression of a solution containing 1 mole of solute

What is the freezing point depression of a solution containing 1 mole of solute in 1 kg of water? (Kf for water = 1.86 °C kg/mol) (2020)

What is the freezing point depression of a solution containing 1 mole of solute in 1 kg of water? (Kf for water = 1.86 °C kg/mol) (2020)

Step 1: Identify the formula for freezing point depression, which is: Freezing point depression = Kf * m.
Step 2: Determine the value of Kf for water, which is given as 1.86 °C kg/mol.
Step 3: Identify the molality (m) of the solution. Since there is 1 mole of solute in 1 kg of water, the molality is 1 mol/kg.
Step 4: Substitute the values into the formula: Freezing point depression = 1.86 °C kg/mol * 1 mol/kg.
Step 5: Calculate the result: 1.86 °C kg/mol * 1 mol/kg = 1.86 °C.
