Level 2 – Data Analysis and Table Reading for Freezing point/Boiling point analysis A student performs a Freezing Point experiment with the intentions of molality of a solution consisting of water dissolved in chloroform. They began by gathering the following table and then executed the experiment as stated below. Table 1. Chemical Properties Table Solvent Normal Boiling Point (oC) Kb (oC/m) Normal Freezing Point (oC) Kf (oC/m) Water (H2O) 100 0.22 0.0 1.86 Benzene (C6H6) 80.1 2.53 5.5 5.12 Ethanol (CH3CH2OH) 78.4 1.22 -114. 1.99 Carbon Tetrachloride (CCl4) 76.8 5.02 -22.3 29.8 Chlorform (CH3Cl) 61.2 3.63 -63.5 4.68 Note: None of the compounds above dissociate into smaller ions.Table is courtesy of http://wps/prenhall.com The experiment was setup as follows: Volume is 0.25 L solvent, the solution and pure solvent density are the same (1g/mL), the solute and solvent are perfectly solubility.At the end of the experiment, the student observed the freezing point of the solution occurred 3.72oC lower than the expected pure solvent freezing point. What would be the molality the solution?
