This episode focuses on gram-to-gram stoichiometry, a practical skill for converting between the masses of different substances in a chemical reaction. They explain a three-step process: convert the given mass to moles using molar mass, use the mole ratio from the balanced equation to find the moles of the desired substance, and then convert those moles back to grams. It emphasizes that moles are the crucial intermediate step, acting as a bridge between reactants and products. The episode provides several examples, including working backward from a desired product mass, and highlights common mistakes and the importance of a methodical approach to these calculations.
