Chapter 8.1, Problem 1LC

Interpretation Introduction

Interpretation: The information provided by a molecular formula needs to be explained.

Concept Introduction: Molecular formula is a way to express the chemical composition of a molecule. In this formula, all the atoms present in the molecule are written in their symbolic representation. For example, the molecular formula of sodium chloride is NaCl.

Explanation of Solution

The molecular formula tells about the total number of atoms of the element present in the molecule of a substance. It confirms the type of atoms as well the number of atoms of the same type present in the molecule. For example, the molecular formula of water is ${\text{H}}_{\text{2}}\text{O}$ ; thus, it can be seen that 1 water molecule contains 2 hydrogen atoms and 1 oxygen atom.

Thus, the molecular formula gives information about the total number of atoms of different elements present in the molecule.
