: All chemical reactions involve atoms and molecules rearranging. To quantify these reactions, we use the mole (mol) . A PDF will guide you through the essential skill of calculating a compound's molar mass by adding the atomic masses of all atoms in its formula. For example, the molar mass of methane (CH₄) is 12.01 g/mol (for C) + 4 × 1.008 g/mol (for H) = 16.04 g/mol. This calculation is the foundation of all stoichiometry, allowing you to convert between grams, moles, and the number of molecules in a sample. Be cautious with files labeled "pdf upd" (updated)
