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...

Assume you have a mixture that is 20% acetone 50% cyclohexane, and 30% dimethyl carbonate. Sketch a GC of this mixture. Label each peak and make each peak roughly the correct size. - correct answers On a graph of abundance vs time, acetone comes off first, then cyclohexane, then dimethyl carbonate. The sizes are in a 2:5:3 ratio. The pKa of benzoic acid is 4.2. At a pH of 2.0, 4.2, and 12.0, in what state(s) of protonation will benzoic acid be? And in which layer (water or organic) would...
