Chapter 12, Problem 12.137MP

Interpretation Introduction

(a)

Interpretation:

Atomic radius of metal atom is to be determined.

Concept introduction:

Atomic radius is measure of size of atoms in molecule. It is mean or average distance between valence electrons and atomic nuclei. Mathematical expression for ideal gas equation is as follows:

$PV=nRT$

Where,

• $P$ is pressure of gas.
• $V$ is volume of gas.
• $n$ is moles of gas.
• $R$ is universal gas constant.
• $T$ is absolute temperature of gas.

Interpretation Introduction

(b)

Interpretation:

Alkali metal should be determined.

Concept introduction:

Atomic radius is measure of size of atoms in molecule. It is mean or average distance between valence electrons and atomic nuclei.

Interpretation Introduction

(c)

Interpretation:

Densities of solid and vapor in ${\text{g/cm}}^3$ are to be determined.

Concept introduction:

Density of crystal is defined as mass of crystal divided by volume of crystal. It is denoted by $\rho$
