Chapter 1, Problem 1.69QP

Interpretation Introduction

Interpretation:

The length of each oil molecule in nanometers has to be calculated using the given data.

Concept Introduction:

Unit conversions:

$\begin{array}{c}\text{1}\text{nm = 1}{\text{×10}}^{\text{-9}}\text{m }\\ \\ \text{1m = 100}\text{cm }\\ \\ \text{1}{\text{cm}}^{\text{2}}\text{=}\text{0}\text{.0001}{\text{m}}^{\text{2}}\end{array}$

Volume of the oil layer can be calculated by the equation below:

$\text{volume}\text{=}\text{surface}\text{area}\text{×}\text{thickness}$
