About this course

Chemistry is the foundation for many scientific and engineering disciplines, but mastering the initial concepts and calculations, especially stoichiometry, can be challenging without focused instruction. This course establishes a robust conceptual foundation in general chemistry, focusing intensely on the mathematical tools and precise problem-solving techniques required for advanced studies. Upon completion, you will possess a strong command of chemical fundamentals, enabling you to approach complex quantitative problems with confidence and accuracy. What you'll learn: * Understand the fundamental laws of chemical combination, matter classification, and modern atomic theory basics. * Master the mole concept, limiting reagents, concentration units, and rigorous dimensional analysis for precise calculation. * Apply stoichiometry principles to mass, volume, and chemical reactions in gaseous, liquid, and solid states. * Practice solving complex numerical problems involving solution concentration and chemical equations. * Learn standard chemical nomenclature and the proper use of significant figures and precision in technical reporting. The course begins with foundational definitions and units, progresses through atomic structure basics, and culminates in extensive practice applying stoichiometry and the mole concept to chemical reactions. This program is designed for absolute beginners or students needing a strong conceptual review before entering college-level science or engineering programs; no prior chemistry knowledge is required. Start building your essential chemistry toolkit today.
