Overview
Understanding mass and composition is fundamental in chemistry as it helps us quantify substances and predict the outcomes of chemical reactions. Molar mass, empirical formulas, and stoichiometry are key concepts that allow chemists to work with chemical equations effectively. By mastering these con...
