Chapter 8, Problem 8.155IME

Interpretation Introduction

Interpretation:

Volume of one mole of potassium using atomic radius has to be calculated and compared with the volume of one mole of potassium obtained from density. The difference in both volumes should be explained

Concept Introduction:

Volume of one potassium atom can be calculated by the given formula

$\begin{array}{c}V=\frac{4}{3}\pi r^3\\ where,\\ r=radius\end{array}$

Density can be calculated as

$Density=\frac{Mass}{Volume}$
