Question
Chapter 8, Problem 74E
Interpretation Introduction
Interpretation:
Whether a light year or a mole of furry moles is longer is to be identified.
Concept introduction:
The standard unit of measuring a length is meter. But the distance travelled by light in one year is calculated by the light year. One light year is equal to

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?
