Interpretation Introduction

(a)

Interpretation:

Interpretation Introduction

(b)

Interpretation:

The number of molecules contained by the ibuprofen bottle is to be determined when the bottle of ibuprofen has 500, 200 mg tablets.

Concept Introduction:

The total number of molecules is determined by the multiplication of the total number of moles with the number of a molecule present in a mole.

This relation is given as

  $totalnumberofmoles\times \frac{6.02\times {10}^{23}molecules}{1mol}$
