Unformatted text preview: the distillation process. What was the appearance of the distillate? How quickly was it collected? Are there any alterations to your experimental technique that you could make to ensure better results? 3. (5 points) Show a sample calculation using interpolation that leads to the % volume of ethanol in your wine sample. Be sure to show all work, beginning with the calculation of density of the distillate! C117 Laboratory: Spring 2012
Experiment 3: Percent Volume of Alcohol in Wine Worksheet 4. (3 points) Compile values of % by volume of ethanol in your wine sample from acceptable distillation runs and list them below. Calculate the average and standard deviation and report them as x s according to the rules from the Laboratory Skills exercise. Comment on the precision of your data. 5. (3 points) Compile values of % by volume of ethanol in the red wine sample from acceptable distillation runs collected by your entire...
