This module introduces students to the quantitative foundations of chemistry through Avogadro’s number and basic molecular calculations. Students learn how one mole relates to the number of particles, molar mass, and measurable laboratory quantities. The session covers converting between grams, moles, and number of atoms or molecules, determining molecular formulas, and applying dimensional analysis to solve chemical calculation problems. This practical lab module strengthens students’ numeracy and precision, building essential skills for later topics in solution chemistry, reactions, and stoichiometry.
