Chemistry deals with the study of matter, and all matter is made up of atoms. Whether you are aware of it or not, chemistry is a part of your everyday life. In this tutorial, we will begin looking at some of the essential principles underlying the chemistry of modern-day life. We will describe some of the fundamental chemical principles related to the composition of matter, including those central to the concept of molecular identity. Also, we will study quantitative aspects of the composition of substances and mixtures.
In summary, we will look at elements, atoms, molecules, ions, isotopes and compounds, and we will learn about the composition of substances and solutions by looking at atomic number and mass as well as moles and molarity.
