Chapter 1, Problem 121AP

Interpretation Introduction

Interpretation: The density of pheromones in a cylindrical air space of given radius and height is to be calculated.

Concept Introduction:

Density is the ratio of mass to volume.

$d=\frac{m}{V}$…… (1)

Here, $d$ is the density in $\text{g/mL}$, $m$ is the mass in grams, and $V$ is the volume in $\text{mL}$.

Volume of a cylinder is given as:

$V=\pi r^{2}h$…… (2)

Here, $r$ is the radius of cylinder and $h$ is the height of cylinder.

One cubic foot is equal to $28.3168\text{ L}$.

The conversion factors for this are $\frac{\text{1mi}}{\text{5280ft}}$ and $\frac{\text{5280ft}}{\text{1mi}}$.
