Document Summary

The purpose of the colligative properties lab was to find colligative properties and gain a better understanding of them. This was to be done by dissolving an unknown substance in a solvent and determining the molar mass of the unknown by using a known freezing point constant and the change in freezing point. The results from the colligative properties lab showed a change in freezing/melting point. In this case the freezing point was lowered. The melting/freezing point for t-butanol by itself was approximately 22 degrees c. the melting/freezing point for t-butanol with the unknown d was approximately 1 degrees c. By using the change in freezing/melting points it was determined that the molar mass of. After referring to figure 0. 2 in the lab notebook it was decided that unknown d was 1-propanol because the molar mass calculated was closest to the molar mass of 1-propanol.
