Chapter 5, Problem 102E

Interpretation Introduction

Interpretation:

The molecular formula of the compound that contains nitrogen and oxygen is to be determined.

Concept introduction:

Formula mass is calculated by the formula as follows:

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

The actual number of atoms of each element presents in the molecule of compound is represented by the molecular formula.
