Molecular Formula | How to Find Molecular Formula
What is molecular formula | A molecule is a smallest unit of a substance which exists independently and exhibits all the properties of that substance. We can represent a molecule by a formula in the terms of symbols and the…
What is Empirical Formula | How to Find It
In chemistry, a chemical formula is a group of symbols of the same or different elements which represents one molecule of the substance. It basically represents chemical composition of the substance. There are three types of formulae in the case…
Chemical Formula | How to Write Chemical Formula
In chemistry, a chemical formula is a shorthand way of describing a chemical compound, or a molecule with the help of symbols and valency of elements. It is one of the fundamental aspects of chemistry. In other words, a chemical…
Percentage Composition Formula in Chemistry
In chemistry, percentage composition is the mass percentage of each component element present in any compound. The percentage composition (or mass percentage) of each element is equal to the mass of that element divided by the total mass present in…
What is Mole in Chemistry | Molar Mass, Example
We commonly use a unit dozen or unit gross for counting of materials or goods. For example, one dozen pens means 12 pens or one dozen bananas means 12 bananas. Similarly, one gross books means 144 books or one gross…
What is Molecular Mass: Definition, Example
In chemistry, molecular mass is an important property of molecules that are concerned with their physical and chemical properties. It is a measure of the total mass of all the atoms in a molecule. Understanding molecular mass is an important…

What is Atomic Mass of Element | Atomic Mass Unit
As we know that atoms of all elements are extremely small. We cannot see them either by the naked eye or even by the powerful microscope. Absolute (or actual) masses of atoms of elements are very, very small. Therefore, it…
What is Molecule | Types of Molecules, Example
Molecules are essential building blocks of everything around us. They are tiny particles that comprise atoms bonded together in a specific way. Molecules are the foundation of all living things and non-living things. Understanding what a molecule is and how…

Avogadro’s Hypothesis: Applications, Example
In accordance with Dalton’s atomic theory, atoms of distinct elements react with each other in the simple ratios. Gay-Lussac proposed that gases react with each other in the simple ratio of their volumes, provided all gases are at the same…
John Dalton’s Atomic Theory: Postulates, Drawbacks
In 1808, An English scientist John Dalton proposed the first scientific theory of matter. This theory is also known as Dalton’s atomic theory of matter. This atomic theory is mainly based on the laws of chemical combination. The main postulates…
