Module 6: Quantitative Chemistry - The Language of Chemical Measurement

Quantitative chemistry focuses on measuring and quantifying substances in chemical reactions, with the mole serving as a fundamental unit for this purpose. By bridging the microscopic scale of atoms and molecules with measurable quantities, chemists employ molar mass to link mass to moles and the number of particles. Stoichiometry provides a framework for calculating the relationships between reactants and products in chemical reactions, utilizing balanced equations to derive mole and mass ratios essential for accurate chemical accounting.
