Chapter 10, Problem 119AP

Interpretation Introduction

Interpretation:

The molecular radius in picometer is to be calculated.

Concept Introduction:

The formula to calculate the volume is represented as follows:

$V=\frac{4}{3}\pi r^3,$ since the molecules are considered to be sphere.

Here, $V$ is the volume and $r$ is the radius.

The number of molecules in a mole is always equal to the Avogadro’s number.
