To estimate the value of n in the chemical formula and to prepare a graph

b)

Interpretation Introduction

Interpretation:

The retention factor for the unknown has to be calculated.

Retention factor:

The time that is necessary to elute that peak minus the minimum possible time for the travel of unretained solute through the column is called as retention factor. The retention factor is calculated using the equation,

$\text{k=}\frac{{\text{t}}_{\text{r}}{\text{-t}}_{\text{m}}}{{\text{t}}_{\text{m}}}$

Where,

${\text{t}}_{\text{r}}$ = retention time

${\text{t}}_{\text{m}}$ = minimum possible time for the travel of unretained solute through the column.

To calculate the retention factor for the unknown
