Mole concept, molar mass

Introduction to Avagadro’s Number The term “Avogadro’s number” is firstly described by a physician in French named  “Jean Baptiste Perrin”. Based on his research on Brownian motion, Perrin estimated its approx value in 1909. However, “Josef Loschmidt” became the first to estimate the correct value of particles in a given volume of any substance.  Avogadro’s […]

What is Avogadro’s Law? Avogadro’s Law describes the link between the volume of a gas and the number of molecules it contains. It was created in 1811 by an Italian physicist named Amedeo Carlo Avogadro. He discovered that equal amounts of different gases have an equal number of particles through a series of studies.  In

Henry Gwyn-Jeffreys Moseley’s historic study in the 1910s gave rise to the concept of atomic number. Moseley used x rays to bombard a variety of chemical elements and observed the pattern generated by the reflected rays. He discovered that as atomic mass increased, the wavelength of reflected x rays reduced in a predictable fashion. The

It doesn’t matter how small or huge a particle of matter is; every particle of matter has some quantity of mass connected with it. The atomic mass of a particle is the amount of mass it contains. In accordance with the international agreement, this is often stated in terms of a unified atomic mass unit

Numerous substances and elements in our environment offer a rare opportunity to learn about their properties. Our understanding of these substances will be improved if we investigate their various properties. Molar mass is the most important factor in understanding the properties of these substances. Whatever the state of a substance is, it tends to behave

The quantum mechanical action of electrons determines the shape of molecules. The sort of bonds between the atoms that make up the molecule can be understood using the valence bond approximation. Molecular geometry is the study of how molecules generate three-dimensional structures and how these shapes relate to chemical reactivity and physical properties. The form
