Chapter 5, Problem 5.175IME

(a)

Interpretation Introduction

Interpretation:

The mass of $\text{Hg}$ vapor present in the type of long, thin fluorescent tubes used in offices has to be estimated.

Concept Introduction:

The volume of a cylinder $\text{V}$ is given by

  $\text{V=}{\text{πr}}^{\text{2}}\text{×}\text{l}$

Where $\text{r}$ is the radius and $l$ is the length of the tube

Ideal Gas Law:

The ideal gas equation is:

  $\text{PV = nRT}$

Where,

P is the pressure

V is the volume

T is the temperature

R is molar gas constant

n is the mole
