Textbook Question
Chapter 9.9, Problem 9.24YT
Examine the values in Table 9.4 from the American Chemistry Council (ACC).
- a. Are these values comparable to those quoted by the EPA in Your Turn 9.20? Assume that the tons quoted were short tons; that is. 2,000 pounds per ton.
- b. The EPA reported the amounts recycled using one unit (million tons), and the ACC reported in another (million pounds). Several explanations are possible. Propose one.
