Chapter 2, Problem 2.1P
Interpretation Introduction

Interpretation:

The term "composition of material" is to be defined.

Concept introduction:

A material is an object which is composed of mixture of substances or of a chemical substance. These can be pure or impure, living or non-living and can be classified according to the physical and chemical properties, their geological origin or functions they perform biologically.

Explanation of Solution

The relative amount of all the elemental species present in a material is known as the composition of a material. Chemical formula such as, empirical or molecular formula can be used to express it.

For example, water is a material composed of hydrogen (H) and oxygen (O) with the formula H2O. This implies that a molecule of water contains 1 atom of oxygen and 2 atoms of hydrogen which is the chemical composition of water.
