Chemistry Lab Report Experiment #: 8 Title: Molecular Mass Purpose: Estimation by freezing point depression. Procedure: 10.0 mL of cyclohexane is measured; this is the solvent. The cyclohexane is then transferred into a test tube. The test tube is fitted with a special stopper and there is a special hole that has a wire to help stir and is also fitted with a thermometer. The test tube is then inserted into a beaker containing a mixture of ice and salt, this creates a cold bath. The salt i...
