Chapter 5, Problem 101E

Interpretation Introduction

Interpretation:

The molecular formula of the compound which contains only sulfur and fluorine is to be determined.

Concept introduction:

Formula mass is the average mass of the compound. Formula mass is calculated by the formula as:

$\begin{array}{c}\text{Formula mass}=\left(\begin{array}{l}\text{atoms of first element in the chemical formula }\times \\ \text{atomic mass of first element}\end{array}\right)\\ +\left(\begin{array}{l}\text{atoms of second element in the chemical formula }\times \\ \text{atomic mass of second element}\end{array}\right)\\ +\mathrm{........}\end{array}$

The molecular formula signifies the actual number of atoms of each element present in the molecule of the compound.
