General Topics & Mole Concept

This collection helps you comprehend Stoichiometry: Mole Concept Basics. It begins by highlighting why we study Stoichiometry. It will give an outline of Stoichiometry. It focuses on the essence of Atomic Mass, Mole and Molar Mass. It also educates us on definitions and understanding of Molecular Mass and Molar Mass. This will let you grasp the subject and get rid of misconceptions, if you have any. The next part of the collection gives an analysis of the relation between Mole, Number of Particles and Mass of Substances. Next, we will encompass the relation between Mole and Volume of a substance. We will also have a broad view of problems based on the relation of Mole with Mass, Number and Volume of particles. Then there is an overview of dealing with the idea of Percentage Composition by mass of an element in a compound, which will also help us learn the application of this concept. Then we gain insight of the Percentage Composition by a number of a substance in a mixture. Then the collection highlights the significance of Stoichiometric Coefficients, Unitary Method and its application in solving problems. This forms the basis of the concept of chemical calculations in Stoichiometry. We learn that Gravimetric means the measurement of masses. In the case of Gravimetric Analysis, we learn the relation between the amount of one reagent and the amount of another reagent. These relations can be of three types such as Mass-Mass relation, Mass-Volume relation and Volume-Volume relation.
