Question CI.27: The plastic known as PETE (polyethyleneterephthalate) is use...

The plastic known as PETE (polyethyleneterephthalate) is used to make plastic soft drink bottles and containers for salad dressing, shampoos, and dishwashing liquids. PETE is made from terephthalic acid and ethylene glycol. Today, PETE is the most widely recycled of all the plastics. In one year,1.5 × 10^9  lb of PETE are recycled. After it is separated from other plastics, PETE can be used in polyester fabric, door mats, and tennis ball containers. The density of PETE is 1.38 g/mL.(2.6, 2.7, 14.3)

a. Draw the line-angle formula for the ester formed from one molecule of terephthalic acid and one molecule of ethylene glycol.

b. Draw the line-angle formula for the product formed when a second molecule of ethylene glycol reacts with the ester you drew in part a.

c. How many kilograms of PETE are recycled in one year?

d. What volume, in liters, of PETE is recycled in one year?

e. Suppose a landfill holds 2.7 × 10^7 L of recycled PETE. If all the PETE that is recycled in a year were placed instead in landfills, how many would it fill?
