Chapter 4, Problem 7PP

Interpretation Introduction

Interpretation:

The number of molecules of acetylsalicylic acid present in one aspirin tablet is to be determined.

Concept Introduction:

The number of molecules is determined as follows:

$n=\frac{m}{\text{MM}}\times {\text{N}}_{\text{A}}$ ……(1)

Here, $n$ is the number of molecules, $m$ is the given mass, $\text{MM}$ is molar mass, and ${\text{N}}_{\text{A}}$ is Avogadro’s number having a value $6.022\times {10}^{23}{\text{mol}}^{-1}$ .
