Andrew T. Hedrick Chem 32 Section S 12/6/02 Experiment 12 – Crystal Models of Metals and Ionic Compounds Purpose:  To determine the molar mass of an unknown substance by dissolving  it in a solvent with known freezing point constant and measuring the change in  freezing point constant and measuring the change in freezing point. Experimental Plan:  The instructions for this plan were based on The  Thompson  General Chemistry 2  Lab Manual, pages 132-136. There were no changes in this  lab plan. Data and Observations: Flask: 25.87g Flask + Butanol: 49.9g Test Tube: 30.75g Butanol mass: 24.03g Test Tube + Flask + Butanol: 54.57g Test Tube + Butanol: 54.78g Freezing Point (pure): 25.056°C Unknown B mass: 2.65g Freezing Point (Trial 1): 17.361°C Freezing Point (Trial 2): 13.729°C Our normal computer locked up constantly, in the middle of data collection We moved to Computer 5 and started data collection over (using the same
