55. A typical rate of deposit of dust ("dustfall") from unpolluted air is 10. tons per square mile per
month. What is this dustfall, expressed in mg per square meter per hour? Assume 1 ton = 2000. lbs. and
1 month = 30 days.
About two centuries ago, Benjamin Franklin showed that 1teaspoon of oil would cover about 0.5 acre of still water. If you know that 1.0 x 104 m2= 2.47 acres and that there is approximately 5 cm3 in a teaspoon, what is the thickness of the 0.5-acre layer of oil? How might this thickness be related to the sizes of molecules?
