Chemistry - Molecules and their Composition

Molecules are made up of atoms and are the smallest particle in a chemical element or compound. This course will introduce you to the fundamentals of molecules and their composition. You will study molecular formulas, which are essentially the actual number of atoms in a molecule, and empirical formulas that tell you what people have observed. You will also study the mole as a unit of measurement and Avogadro's number, which is equal to 6.023 × 10 to the power of 23, and is the constant of proportionality.

You will then study molecular and empirical formulas from the mass composition and learn how to balance chemical equations. This course will also discuss stoichiometry, which is the study or the calculation of the relationships between the different molecules in a reaction. You will learn about the limiting reagent, which is basically the reactant that produces the least amount of product. You will also master how to solve mass composition problems.

Learning how to convert between atomic mass and grams using Avogadro’s number or the mole is one of the important topics you will study in this course. Once you have mastered this, you will be able to easily work out ratios and weights of molecules. You will also learn how to balance chemical equations and get viable reactions by balancing the reactants within equations. So, check out this course and learn more about stoichiometry today!
