Chapter 8, Problem 115E

(a)

Interpretation Introduction

To estimate: The densities of argon and xenon.

(b)

Interpretation Introduction

To estimate: The density of the element with atomic number 118.

(c)

Interpretation Introduction

To estimate: The mass and the average density of a neon atom, to explain the comparison of this density with the density of neon gas, and to give a suggestion about its nature.

(d)

Interpretation Introduction

To determine: The number of atoms of each element in a volume of $1.0\text{ L}$, and to estimate the number of atoms found in $1.0\text{ L}$ of $\text{Ar}$, and calculate the density of $\text{Ar}$.
