Can someone help me answer the the blank components in the data sheet here. I'm really unsure of how to calculate these variables including accepted MW and percent error Procedure B. Det A. Calibration of Thermometer with Pure tert-Butanol The solvent for this experiment will be tert-butanol. Since you do not have a calibra thermometer or carefully purified tert-butanol, your measurement of tert-butanol's freezin probably not agree with the literature value shown in Table 1 above However, you are in temperature changes. Therefore, the first step will be to determine the freezing point of with your equipment put t of the solven neare Recor The i you are only interes Reco C. D Fll a -in test tube about half full with tert-butanol. Keep this test tube in a beaker of water at 30-35 °C until ready to use so that the alcohol does no app test solidify. Do not overheat as this will cause substantial evaporation. solv â-Thermometer Wire Stirrer â Water ( Ï Â°C -Bath Figure 2 Set up the apparatus as shown in Figure 2.
