Foundations of Chemistry: Basic Concepts and the Mole Concept

Chemistry can feel overwhelming when you are introduced to complex formulas and abstract calculations all at once. Building a strong foundation in the core rules of measurement and chemical behavior is the key to unlocking your confidence in science. This written course guides you step-by-step through the essential building blocks of chemical science, ensuring you understand the reasoning behind every formula. You will transition from memorizing terms to confidently solving stoichiometry and unit conversion problems. What you'll learn: - Understand key terminology, scientific notation, and the international system of units (SI). - Apply the laws of chemical combination to predict how elements react and combine. - Master the mole concept and perform calculations involving molar mass and Avogadro's number. - Determine empirical and molecular formulas from experimental data. - Calculate solution concentrations using molarity, molality, and mole fraction based on modern IUPAC standards. - Analyze chemical equations to solve practical stoichiometry problems. You will begin by exploring fundamental definitions and measurement standards before moving on to chemical laws, molecular calculations, and practical problem-solving techniques. Through clear written explanations and step-by-step text-based practice exercises, you will develop a practical grasp of these core concepts. This course is designed for absolute beginners, introductory science students, or anyone looking to refresh their scientific foundations. No prior chemistry knowledge is required.
