Haydon ConnettCHM151 32253Lab 15Freezing Point DepressionPurposeThe purpose of this lab is to determine the concentration of a solution by determining its freezing point and comparing that to the freezing point of the solvent. Materials10mL Graduated CylinderStyrofoam CupDistilled Water90% Ethyl Alcohol70% Isopropyl AlcoholLarge Test TubeIceRock SaltThermometerProceduresTake the styrofoam cup and fill the bottom with ice and salt. Measure out 2mL of ethyl alcohol and put it in the large test tube. Measure 10mL of distilled water and add to the test tubeand mix. Place it in the styrofoam cup, cover it, and carefully fill the cup with ice and rock salt. Remove the cover and place the thermometer in the tube. Every minute, record the temperaturefor 39 minutes. Rinse out the test tube and repeat. Now do it two more times with isopropyl alcohol. Next, using the freezing point temperature for each trail, calculate the molality assuming the waters freezing point is -1.86 celsius. After the molality is determined, determine how many moles of alcohol is in the solution. Convert that to grams. Now, taking the mass in grams, divide
