Determine the density of three pure solids on g/cm3. Choose objects of which you are sure of their identity, such as
aluminum foil (crumpled or in a ball), copper wire or iron nails. Then, test an object that you think might contain one of
the materials you tested.
Report as to whether your data supports your hypothesis. Write a 200 word report including hypothesis, procedure,
results, and conclusions. Discuss the question, "What factors cause differences in density?" Be specific.
Example: If you choose aluminum foil and test its density by doing a water displacement test. You could then choose a
soda can or a can that contained some fruit, vegetable, or soup and test the can.
Example: If you choose to test copper wire, you could use a penny for your second test to see if the penny is pure
copper.

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
