What is the freezing point depression constant of lauric acid?
the freezing-point depression follows a simple direct proportionality relationship: ∆Tf = Kf·m (1) where the proportionality constant, Kf, is called the molal freezing-point depression constant. Lauric acid (the solvent in this experiment) has a reported Kf = 3.9 °C·kg/mol = 3.9 °C/m.Click to see full answer. Likewise, people ask, what is the freezing point of…

Likewise, people ask, what is the freezing point of lauric acid? 43.2 °C Likewise, how do you calculate freezing point depression? Strategy: Step 1: Calculate the freezing point depression of benzene. Tf = (Freezing point of pure solvent) – (Freezing point of solution) Step 2 : Calculate the molal concentration of the solution. molality = moles of solute / kg of solvent. Step 3: Calculate Kf of the solution. Tf = (Kf) (m) In this way, what is the freezing point depression constant? Kf is the molal freezing point depression constant of the solvent (1.86 °C/m for water). m = molality = moles of solute per kilogram of solvent.What is the freezing point of benzoic acid? 122.3 °C
