Separating Plastics Based on Density The diagram below shows three liquid layers in a beaker. The liquids are hexane \( (\mathrm{d}=0.659 \mathrm{~g} / \mathrm{mL}) \). mechylene chloride \( (\mathrm{d}=1.33 \mathrm{~g} / \mathrm{mL}) \), and water \( (\mathrm{d}=1.00 \mathrm{~g} / \mathrm{mL}) \). Label each liquid on the lines on the right hand column. Record where the samples of aluminum, PETE, and HDPE come to rest in the beaker in the lines on the left hand column. Based on this observation, which plastic has the higher density, PETE or HDPE? Youcan conclude that the HDPE is more dense than [hexane I water I methylenechloride] and lessdense than [hexane I water I methylene chloride] (circle the correct response). 4. Separating Plastics Based on Density (d) Based on the densities of the solids to the right, where do you think these materials will come to settle once added to the graduated cylinder to the left? Record this in your lab manual under Instructor Demonstrations \( \$ 4 . \)
