1. This experiment.
2. The appropriate sections of your textbook.

1. A solution contains 0.10 mL acetone per mL. The solvent is water. The density of acetone is 0.790 g/mL. What is the concentration of the solution in mmoles acetone per mL?
2. 0.4 microliters of the solution in 1) is injected to a GC, and gives an acetone GC signal with area 20.5 units. A solution with an unknown acetone concentration gives a signal with area 16.8 units with the same size injection. How many moles of acetone were injected? What is the concentration of the unknown solution in mmole/mL?
3. A mixture is known to contain some or all of the following liquids:
   
   water
   acetone
   ethanol
   isopropyl alcohol
   methyl ethyl ketone
   
   You decide to analyze the mixture by GC. Describe the necessary experiments.
